I recently tried to load into my Minecraft account after installing the Windows 10 May 2021 update. When I loaded the game, it came up with an error message as you will see in the attached image below. I tried updating my drivers (both of which were up to date) and that had no effect either. I deleted my mods, I uninstalled and reinstalled, I ran as an admin, I even reinstalled Java. All of these had not worked to fix my game, after contacting support, there was still no success, and I was directed here. I don't know if this is a bug on Windows' end, or on Mojang's end.
