found an other post OS Stop Run-Time Critical Stop - General Support - Unraid
with same error and motherboard and was suggested to change
Macvlan call traces are usually the result of having dockers with a custom IP address and will end up crashing the server, switching to ipvlan should fix it (Settings -> Docker Settings -> Docker custom network type -> ipvlan (advanced view must be enabled, top right))
dont understand if this is the problem why it started under datarebuild but anyway have tested to change this setting also to see if that solves it
