UE4 constantly crashing when trying to play game

Community Community & Industry Discussion

I’ve recently updated my windows 10 (system updates) and now my project will not play (builds/compiles fine in both UE4 and VS). I’ve tried restarting my PC, deleting all files/directories except for config, content, source folders, and the .uproject file. UE4 v18.1 will crash when trying to play the game with the following log entries (just the top):

Try this solution. I was facing the same problem and I describe how to resolve it:

I actually am doing this right now, I just found it. I’ll let you know what happens. Also, do I have to implement anything into my build.cs?

Woops, did not mean to bump this. Thought this was a reply to my post on another topic.

Hum so what i need to to, what does mean “rebuild VS files” ?

[FONT=&amp]I try all the method in the link except last one, where is “\UnrealEnginePython” Folder? My Engine is 4.23.1 build from source but I didn’t find that folder you mentioned, my problem is that when I try to save a actor called BeaconManager, it crashed with pic and in the crash log is same error with you guys, is anyone know this?

I all. Not sure if this helps, but I had similar problem and fixed it by creating a new empty project and copying the contents of the “Content” folder from the old project into the new one.
