Over the last week I have been unable to load Microsoft Edge or Brave browsers; both were working fine. I installed Firefox and this is working fine, but not my preferred browser. I just installed Opera and that too will not load.
Recently, several issues with Chromium-based browsers (e.g., Brave, Chrome, etc.) have been reported here in the forum. The only browser that worked without issues for the users affected by this error was Firefox.

You can also try to launch the browser via terminal and disabled hardware acceleration:
I ran it from flatpak. Deleted it then went back to the sotware store and chose the flatpak version to install. guess I will have to fight another day to find a solution.
