Edge Browser doesn't start anymore

Question

Edge Browser doesn't start anymore

Markus Obergfell 10

After the latest update, Edge stopped working. I cannot open it anymore. Instead, it opens the Firefox browser. When I set standard apps to Edge, Firefox would't start anymore when I try to open Edge but Edge doesn't start either. It just doesn't happen anything. Please help. Thank you, Markus

We are having issues with version 143.0.3650.75 specifically in our Org, unable to browse. Spinning wheel on all websites unless we open In-Private session. Or we delete the User Data folder under %appdata%\Local\Microsoft\Edge - This works until the browser is restarted. Then the problem with web pages starts again.

Thanks for the clarification.

I haven't seen any other cases where Edge stopped working after installing the latest update. Your case may be isolated.

I suggest you restore Windows to the point where Edge was working properly.

Press "Windows + R", type RStrui and press Enter;
In the "Restore System Files and Settings" window, select "Next".

Note: If on this screen you have two options to choose from ("Recommended restore" and "Choose a different restore point"), see if the "Recommended restore" is from before the problem started to occur. If so, select "Search affected programs" and proceed as in step 4. Or select "Choose a different restore point" to see the list of available restore points and proceed to Step 3.

Select the restore point you want to use from the list of results, then select "Search affected programs".

Note: If you don't see the restore point you want, check "Show more restore points".

You will see a list of items that will be deleted if this restore point is performed. If you are satisfied with the exclusions, select Close > Next > Finish.

Then, wait for the procedure to finish. Your computer will restart.

Windows will restart to apply the chosen restore point. After Windows starts, see if the problem is fixed.

Note: System Restore does not affect your documents, images, or other personal data.

Let me know the result.

Feel free to ask back any questions.

Unfortunately, this feature was not activated on my PC. There is no restore point available.
I would like to add something: I thought that there was an update running and after that, the edge browser stopped working, but: I checked the recent installed updates and the latest was .NET Framework update some days ago. The reason, why I thought that there has been an update was that I left my PC in Sleeping mode with power cable connected. After I came back some hours later, Windows had restarted and all apps were closed. That was the reason why I thought the "problem" was the latest update. Because after that event, Edge stopped working. But now I wonder what really caused Windows to restart when it wasn't an update... I try to check some logs if there are any...

I can check the log to see if I can find any clues as to what might have happened.

Export and share the log for analysis:

Press Windows + X and select Event Viewer;

Expand Windows Logs and select System;

In the Actions panel on the right, select Save All Events As and save in an easily accessible place.

Then, upload the file to the cloud (OneDrive), choose to share it, and get the link.

Post the link to the file here so I can have a look.

The log may contain multiple entries, so providing the approximate date and time of the issue would help me identify relevant clues. Please also share your time zone, since the logs always display the viewer's local time, regardless of the originating PC's time zone.

I await your reply.

Hi, I thin I found the solution: I had a small program running naming MSEdgeRedirect. I had it for some months now and did its job. But it seems it just wouldn't work properly since yesterday. After I de-installed it and re-installed Edge, everything worked just fine. Oh man, that's almost embarrassing. But hopefully, everything is working again. Thank you very much for you help!!

Look for Microsoft Edge, click on the three dots, and select "Modify";

Hi, I already tried this. Also I tried a complete reinstall, sfc /scannow and other workarounds

What is the current version and "OS Build" of your Windows 11?

Press "Windows + R", type winver, and click OK.

If you prefer, share a screenshot. Use the shortcut "Windows + Shift + S" to use the screenshot tool.

Be sure to censor your email address if it appears. The Microsoft Q&A is public.

I await your reply.

If Microsoft Edge is not starting after the latest update, it may be due to a known issue with the browser. Here are some steps you can try to resolve the problem:

Check for Updates: Ensure that your version of Microsoft Edge is up to date. Sometimes, issues are resolved in subsequent updates.
Reboot Your Computer: A simple restart can sometimes fix issues with applications not launching.
Reset Edge Settings: If you can access Edge settings, try resetting them to default. This can help if there are configuration issues.
Reinstall Edge: If the above steps do not work, consider uninstalling and then reinstalling Microsoft Edge. This can help resolve any corrupted files that may be preventing it from launching.
Check for Conflicting Software: Sometimes, other software can conflict with Edge. Ensure that no other applications are interfering with its launch.
File a Bug Report: If the issue persists, consider filing a bug report through the Feedback Hub app, as this may help Microsoft investigate and resolve the issue in future updates.

If these steps do not resolve the issue, please provide more details about any error messages or behaviors you observe when trying to launch Edge.
