UE4 version 4.19.2 project crashes on startup

So today as usual i open Epic Games Launcher and start up my College assignment work-in-progress scene,and it crashes,again and again.
Made a copy of the scene folder and tried deleting Intermediate and saved folders,still no luck, I really need your help folks! I am due to submit this huge scene in 2 weeks and there could’nt have a been a worse time for this to occur!

Your crash report doesn’t say anything. Do you have a log? Try installing debugging symbols for your engine version and then show me which errors occur.

Hye there Sensei,i have updated my engine version to 4.21.2,and the project seems to open normally as before.Thanks for the help nonetheless!
