Check your project log when you boot the editor to see what its getting stuck on
Try to remove Intermediate/Saved/DerivedDataCache folders (and maybe Config too ?)
Would this delete anything in the project? I would hate to lose the progress I have made…
You can delete Intermediate, saved and DerivedDataCache safely, it’s mainly stuff that get’s generated and cached on loading your project. Also might want to verify your UE5 from Epic games launcher
Unfortunately, it is still stuck at 92%.
Does your log file say anything about it in Saved\Logs ?

Edit: I noticed that when I try to load the project, it starts loading, but then the dots after Loading Startup Map: /Game/FIrstPerson/Lvl_FirstPerson freeze. Any ideas?
You could try to load into an empty level.
To do that, remove the level path in EditorStartupMap in …\Config\DefaultEngine.ini
Once the level is loaded, you can try to load your Lvl_FirstPerson. Maybe it provides additional insight.
