Need help with an error...: "Error: begin: stack for UAT"

this is a strange error ;o

-ProcessResult.StdOut: LogInit: Display: Failure - 42 error(s), 29 warning(s)-

now that’s a lot of errors lol,
did you consider fixing them?
like reimporting the materials and the mesh’s you have, re-saving/re-naming the assets, fixing re-directory files.

now I faced similar problem like this before,

you know what I did? I created a new project because the old one had too many deleted but still exist in the project directory files in windows, lots of moved files and some plugins were Out-dated.

now I wouldn’t come here to post something you already know the problem of, because it says it in the logs, it gives you the file directory and the issue as well, go fix them and if you cant, you can do what I did, created a new project and do the same thing with of course testing each time you add a plugin or a punch of assets.

This : *I deleted already the Saved, Binaries and Intermediate folder without effect. Has tons of effects in my experience, keep in mind if you cook your project it wont include those files or saved files, but uses them to reference assets and other stuffs such as files, materials etc.

You Must Keep Compressed Zipped Backups For Your Project Before You Do Something Like The Above.

That’s My Opinion Sir.
