App doesn't start with root. Can't find cause

I am running a rooted Galaxy S20 with BeyondROM 6.3 and Magisk 27.0. My banking app is working fine after I enabled hiding the Magisk app and adding my banking app to the deny list. Now the problem is that I can't start the app from my health insurance and I just can't figure out why. It's [this](https://play.google.com/store/apps/details?id=de.barmergek.serviceapp) app. Every time I'm starting it I just get stuck on the loading screen and it's even so bad that my phone is frozen for some seconds. I'm pretty sure it has something to do with my rooted device since they even say in the app infos on play store that you can't use it with a rooted app. How can I get this thing to work? Output from logcat for some seconds after starting the app: https://file.io/f0b7aTrQqm6V (had to upload it because the file is too long otherwise) In Line 94 it starts with

02-17 18:56:40.593  7429  9046 I Pageboost: start alp : de.barmergek.serviceapp

and then in lines 119 & 120 we have:

02-17 18:56:40.620  7429  7522 I ActivityManager: Start proc 17694:de.barmergek.serviceapp/u0a383 for activelaunch {de.barmergek.serviceapp/de.barmer.serviceapp.viewlayer.activities.NativeSplashActivity}
02-17 18:56:40.626 17694 17694 I Magisk  : zygisk64: [de.barmergek.serviceapp] is on the denylist

which is the standard activity to start the app and the confirmation that the denylist is working. Maybe line 193 can give some additional information:
