Tor Browser ended with non-zero (error) exit code!

I got this error on one of my workstations in qubes-whonix.
Is this an indicator of compromise on that vm?
Or is this just some bug? It’s only happening in one vm.

[ERROR] [torbrowser] Tor Browser ended with non-zero (error) exit code!

Tor Browser was started with:
/home/user/.tb/tor-browser/start-tor-browser.desktop --allow-remote .

Tor Browser exited with code: 127

To see this for yourself, you could try: Start Menu → System → Xfce Terminal
Then run:
