Good day! I'm Raniel. I understand your frustration regarding this issue and I'll do my best to help.
Just to clarify, did you make any changes to your machine before encountering this issue (like installing third party apps, recent updates, etc..)?
Double-check if your machine doesn't have any pending security patches: Go to Start > Settings > Update & Security > Windows Update > Check for Updates.
Once done, aside from reinstalling the browsers, can you also perform the additional methods on this article: https://windowsreport.com/cant-download-files-w...
Another option is to enable the built-in administrator account to isolate the issue
- On the Windows sign-in screen, press and hold the Shift key, then select Power > Restart
- After your machine reboots, click on "Troubleshoot" under Choose an option
- Click on "Advanced options" > select "command prompt"
- On the command prompt window, type
net user administrator /active:yesand press Enter
If that didn't work, kindly perform the 5th method on this article on how enable the built-in administrator account: https://www.tenforums.com/tutorials/2969-enable...
- Reboot your machine, then login to your admin account, and check if you'll encounter the same issue.
Note: If you don't encounter the issue on the built-in administrator account, I suggest that you create a new user account (go through the steps under "My computer is in a workgroup") . Please refer to this article as a guide: https://support.microsoft.com/help/14039/window...
However, if the issue persist, kindly perform a repair install of your Windows which fixes the broken system files on your machine. Here is a guide: https://www.tenforums.com/tutorials/16397-repai...
There should be no worries in performing it since you will select the option to keep your files during the process.
I hope this helps. Good luck!
