Android 12 (Oneplus) + Keepass2Android + ykDroid not working

[Friday13th87]

Hello everyone. i am currently using Keepass2Android 1.09d-r0 with ykDroid 1.2.1 on my Oneplus 8 running Android 12 [no custom Rom, so Oxygen OS] and a Yubikey NFC 5C. After installing everything, rebooting, and choosing "Password + Challange-Respond" and selecting the File, there is only popping up the Windows with differend cloud services to select the file but no Popup to scan the Yubikey or something similar. If i Scan my Yubikey nothing is happening, its just asking which application to start.

Is there something i can to to get it fixed? thanks!
