I rooted my VollaOS 12.1 using Magisk with no problems.
After rooting I wanted to lock the bootloader again. But locking the bootloader after rooting with fastboot leads the device into an endless boot-loop. I solved this problem by not locking the bootloader again. This behavior after the rooting seems to be a bug.
My device now works rooted but with still unlocked bootloader. At every booting of the system I get the message:
"Orange State. Your device has unlocked and can't be trusted ...". After that message the device boots normal and works without any problem.
