LogPackageName: Warning: DoesPackageExist called on PackageName that will always return false. Reason: Input ‘’ was empty.
Anyone have any solution to this… I am more of a beginner so please try to reply with the understanding Im still trying to get oriented with everything please.
I have been having the same issue. It only happens in UE 5.2 prev 2 for me. No idea where it is coming from.
did you find any solution?
Having the same issue and getting graphics card crashes when trying to open some of my levels which I suspect is related, did anyone find a solution?
Was hoping the 5.2 release would fix this, but it still occurs. Anyone know of a solution?
It hasn’t any impact on the engine but frustrating.
According to what I saw in another post, this issue is caused by a conflict between the cache generated by the new version of Unreal Engine and the cache from the old version. Simply deleting the files in the ‘C:\Users\AppData\Local\UnrealEngine’ folder should resolve the problem. It worked for me.
Kugelspritz’s solution worked for me as well. Thank you for contributing it.
Keep in mind this will also reset many of your editor preferences and delete your compiled shaders, so… you know what that means. 
Deleting folder didn’t help. Still occurs for me.
Same here, nuking the folder made no difference.
Worked for me, thanks.
I’ve been having this issue as well and I tried this but didn’t work. For the people it did work for, did you delete the .bin, common, editor, and intermediate folders as well the engine folders located within ‘‘C:\Users\AppData\Local\UnrealEngine’’? I only deleted the 5.2 and below folders but left the .bin files, common, editor, and intermediate folders because I didn’t think that was necessary and possibly could mess things within the directory. Any advice for this annoying bug would be awesome!
Yes, I deleted everything that was in ‘‘C:\Users\AppData\Local\UnrealEngine’’. Only after that did it work.
Didn’t work for me.
However this did.
