the VM crashed (the Assertion messages indicate the reasons). could you post the VM and storage configs as well?

I'd suggest switching to virtio-scsi instead of virtio-block, and install the latest round of updates including kernel (there have been some issues with io_uring that might have caused this behaviour).
 
we're always updating nodes asap. but usually ain't able to reboot it for a long time to boot new kernel.
