How do I fix the YAML error?

I’m using version 5 of Unity and I’m getting an error in a YAML file. The error is “Unable to parse YAML file: [mapping values are not allowed in this context] at line 1” This comes up every time I open the engine.

I’ve seen some say to open the YAML file and change some stuff in it. But I can’t even find the YAML files. I’ve also seen that it’s caused by meta file issues and version control. The project is local but I don’t know if it matters if it’s local or cloud based.

Does anyone have a solution for this issue?

I believe you don’t need this anymore, anyway, just for future researches this solution worked for me.


Resuming the video, go to ProjectSettings folder and delete the file ProjectVersion.txt. When you open the project again it will generate a new .txt

OBS: Just remember to always create backups before.
