It sounds like you've already tried a comprehensive list of troubleshooting steps for Microsoft Edge. Since Edge is not appearing in Task Manager and there are no logs indicating it is starting, here are a few additional steps you can consider:
- Check for Windows Updates: Sometimes, additional updates may resolve issues caused by previous updates. Go to Settings > Update & Security > Windows Update and check for updates.
- Create a New User Profile: There might be an issue with your current user profile. You can create a new user account and see if Edge starts there. If it does, you may need to migrate your data to the new profile.
- Reset Windows: If nothing else works, you may consider resetting Windows. This can be done by going to Settings > Update & Security > Recovery > Reset this PC. Make sure to back up your data before doing this.
- Use the Process Monitor Tool: If you have access to it, using the Process Monitor tool can help trace what happens when you attempt to start Edge. This might provide more insight into what is going wrong.
- Check Group Policy Settings: If you're on a managed device, certain Group Policy settings might be preventing Edge from starting. You can check with your IT administrator if applicable.
If you continue to experience issues, contacting Microsoft Support may provide you with more tailored assistance.
