Sorry for not including hardware information:
DS3617xs (INTEL Xeon D-1527), 16GB DDR4 ECC SO-DIMM. The disks are all ironwolf 10 to (the unit is not full) and there is a SSD cache (read-only).
I’ve included a screenshot of the resource monitor when PMS becomes unresponsive:
Also I previously add this bug: PMS Crash due to sync tasks?
