Just wanted to report the same issue. I just opened an account at ConsorBank, did you use the app before? Do earlier versions work?

[tobiasKaminsky]

Yes, I use the app since many years, always with MicroG.
They started to use more Google API stuff, which is really not good.

Earlier versions worked, yes.

For now I can live with this workaround:

When I click fast enough on another tab, I can use the app until I go to "Home" or try to open my banking cards within the app.

I got this exact exception in a different banking app, Monterra Credit Union (com.sanmateocu.sanmateocu):
