>From the attached log you seem to run systemd from buster-backports
(247.2-5~bpo10+1). But from their NEWS in the changes done with 247:
* The cgroup2 file system is now mounted with the
"memory_recursiveprot" mount option, supported since kernel 5.7. This
means that the MemoryLow= and MemoryMin= unit file settings now apply
recursively to whole subtrees.
The support for thi was only added in 5.7-rc1 so if you need this you
will need as well the kernel from buster-backports.
