After installing Bitdefender, Kobo eReader no longer recognized by Win 11 PC

After installing Bitdefender I can no longer get my Kobo eReader recognized by my Win 11 PC

It shows up in the taskbar as a USB device with the software version as it's title.

Drive Manager shows it as a drive but without a drive letter and as "Unallocated"

Doesn't show up in File Explorer

Even disabling Bitdefender in "Protection - Antivirus - Advanced" doesn't help.
