App immediately closes even after running the quarantine removal in terminal. Catalina 10.15.6

Trying to get this to work and hit a bit of a wall here, any information would help!

Trying to run 5.3 Alpha 4.8.5

Did you perform the process to the application itself, or the entire folder? It must be done to the entire folder.

xattr -dr /path/to/OutFox

That worked thanks! Must have only tried it on the app itself.
