[Nalev]

Got the same error, unable to get it working. Have you found a fix yet?

[thecocoa]

Have you tried:
./WowUp-CF-2.22.0.AppImage --no-sandbox

Isn't sandboxing only an issue if unprivileged namespaces aren't enabled? Mine was, and still didn't run. It miraculously ran fine after a couple of hours though, not sure what changed.
