Script works properly when launched from terminal, but fails after being executed as a policy. Self Service tries to open, then crashes. App version is 10.35.0, the OS it gets executed from is 10.14.6, fully patched.
The same script fails on a manually upgraded Catalina as well. (Did it for testing purposes, just to see what happens; system is already running 10.15.7).
