Too much technical details, but we we did the necessary development, a new LINSTOR RC1 should follow early next week and I will adapt the plugin during the RC period. So next LINSTOR + linstor-proxmox 7.0.1 should then behave on larger setups again. Sorry for the inconvenience. Probably also a good call for people to test RCs, I do them for a reason.
