Looking at the part
“Failed to parse mp4 “file://F:/Projects/%41E%43B%435%433_%413%430%437%43C%430%43D%43E%432/UE5/Oleg_Gazmanov/Content/Media/003.mp4”

Implies you are probably using letters in your folder that are non-standard for the roman alphabet. Unreal seems to have lots of problems with this resulting in errors, failed builds etc.

Try copying the project to F:\Projects/UE5/Oleg_Gazmanov and see if it works there.

Yes, you’re right, I’ve already solved the problem. Thanks anyway.

Hello, could you tell me how to solve this problem?I had the same problem.
