Gitea crashes when creating new releases.

I am trying to install a new release. My file size is (600 MB). I made all the necessary edits in app.ini. There is no nginx or any other reverse proxy either. I just installed and using gitea on my server according to the instructions. but it crashes. I got this warning once. JavaScript promise rejection: Failed to fetch. Open browser console to see more details.

What’s the Gitea version? And what’s the error? Can you give more details?
