Plus42 Android crashes immediately

[DA74254]

Mostly for @Thomas Okken..
I recently downloaded the latest version of Plus42 for Windows and Android.
Works fine on Win11.
I installed (sideloaded) to my Cat S61 w/Android 9.
It instantly crashes and stops. The app merely flashes on my display and shuts down.
Tried to restart phone, but same, and I get a popup with "Plus42 keeps stopping" and options for "App info" and "Close app".
Any suggestions?
If I get it working, adn when project is properly released, I'll gladly pay for it.
