Game frozen after choosing game folder at first launch

Bug description

So I downloaded lazer through old client. It installed and launched. After installation it asked me to configure my game. When I choose folder for the lazer game, it returned me into a main menu. I was not expecting that and i went back to configure the game though in-game settings. I pressed choose game folder again, selected folder and it froze. The music continued playing, but everything else not

Alt+F4 does not worked, so i killed the process

I'm not sure how you've managed to do this but this sort of migration should not be permissible. Needs investigating.

I think it's realm's blame, not migration's. The threadlock acquired somewhere on sending callback into synchronization context

Sooo... Now I think it's realm's issue 100%. I somehow deadlocked whole game by... starting another migration? while previous migration working on background. By starting new migration, the realm blocked all operations while there was importing tasks.

I think deadlock happened in that 4ms frame. Assume that lock requested while there was running task on importing skin. When the skin imported, realm started to blocking all operation, but all other tasks wasn't done. Other task requested to lock realm, causing dead lock... on both side??

I'm not really sure, because I never looked osu code. It's just my opinion, nothing else

Does the issue only happen when you migrate from and to the same folder? Have you tried doing a migration that makes sense?

I didn't tried to migrate to other folder. After the restart, the game showed configuring menu where I choose same folder. Everything happened as expected without dead locks.

I'll try to repeat the process
