Stuck at Logo after flashing rom

hi,

I'm running official OxygenOS 3.1.3.
Rooted (systemless) , TWRP installed.

I don't have any problems on my rom, but everytime I flash a rom I get stuck at the boot logo.
I can just force reboot, goto twrp and restore my nandroid backup, and my phone works fine again.
But I can't flash any rom.

tried this:
Dirty flash OP3Lite rom - stuck at boot logo
wipe and install OP3Lite rom - stuck at boot logo
Restored nandroid backup, factory format, wipe and install OP3Lite rom - stuck at boot logo
wipe and install FreedomOS - stuck at boot logo
Restored nandroid backup, factory format, wipe and install FreedomOS - stuck at boot logo

Both roms I tried are OxygenOS 3.2.1 stock based, my problem is most likely not due to the rom I want to flash.

Anyone knows a solution for this?
is it possible that systemless root causes this problem?
