How to revive crashed project? Please help.

Hello everyone…
I deleted “intermediate” and “save” folder from UE project because i read somewhere (from UE epic staff guy) that might cause problems with standalone play… after this even if i copied back that folders, project keeps crashing…
If i copy files from backup save to project, it works only once, when i close project, its not possible to open it again…

Could someone please tell me what can i do? i spent on that project over 1000 hours, im totally sick of this.

What does the crash log say?

Crash window nothing (edit: only this You do not have any debugging symbols required to display the callstack for this crash.) but here is .txt file from crash log

edit: “Solved”…
luckyli im making full game backup every 1-2 weeks, so i run older game and copied newer assets to it and it seems its working…
