I am also facing this issue. I have found that if I delete/move the .minecraft folder, I can start the launcher exactly once. If I close it, then upon reopening it I immediately get the “Whoops” screen with the message
ANunexpectedissueoccurred;wearesorryfortheinconvenience.PleasetryrestartingyourLauncher.Ifthatdoesnotresolvetheissue,pleaselog a bugreportHERE
This happens regardless of how far I go through the launcher in that first, successful run. I’ve tried closing it before entering my Microsoft credentials, and also (after again deleting .minecraft) after downloading and starting Java Edition, but before creating any saves.
