I know, reports for unofficial builds restricted, but just for info. Had same issue with spes (Redmi Note 11) and TWRP 3.7.0_12-0 After deleting whole /data/fonts folder backup was successful. At boot fonts downloaded again, no issues. That folder introduced starting Android 12:

UPD: seems this problem acknowledged: https://github.com/TeamWin/android_bootable_recovery/commit/cc683e7a3deefb96ece49b07bf88648087a7ccaf And it's up to device maintainer to add exclusion for /data/fonts
