    Same behaviour on an Entra joined W11 on ARM VM running on MacBook Air M3 and Parallels Desktop Standard 26.4.0.
    After the July update, the first thing I noticed was that there was a problem with the PIN service, I had to enter my password instead.
    Then BitLocker started to pop upon each device start. Then the TPM/vTPM rabbithole begun.
    I deleted the VM, made a new one, also fails, removed/recreated the chip in VM settings, deleted in Keychain. Nothing.
