F-Droid version not working

[noci2012]

Describe the bug, issue or concern

The check app on F-Droid cannot scan QR codes. (Paper at least, possibly all).
Please dont say use the play-store app as this phone has no play-store at all.

To Reproduce

Install F-Droid version of scanner, the QR code is not recognized.
The QR code can be scanned using a generic QR-reader so it is not the camera.
Using a generic QR scanner the resulting gibberish is not usefull.

Expected behavior

At least a scan by the APP.

Smartphone (please complete the following information):

• Device: Pixel 4a
• OS: Graphene OS
• Browser not relevant
• Version up to date, with near weekly updates.

Additional context

Add any other context about the problem here.

Does it give a red screen, or does the QR scanning not work at all?

[noci2012]

QR code is NOT recognized by the check app. It doesn't matter if there is a QR code or something else in view of the camera.
It doesn't matter to rotate, zoom-in/ zoom out, the camera.

The "QR & Barcode Scanner app" (V1.9) from: dmitriy-ilchenko can read the QRcode, but cannot verify it's contents.
