Anyone experiencing session hosts becoming unavailable at random

AndreasJ5325 we also have this issue running Citrix in multi user Win 10 in azure.  Out of 50+ session hosts running per day we get 2 or 3 isssues per week.  Session host becomes unavailable in Citrix, rdp won’t work.  We can still access the machine via unc path to c$ and get to services remotely.  The machine isn’t completely dead but all sessions freeze on it.  Event logs usually show a terminal services failure svchost.  I have been working with MS on a ticket for a few weeks with logs/memory dumps.  the host needs to be rebooted to bring it back to a working state.  It could be down to certain we redirect as we also usually see audiobuilder service issues around the same time but that could just be because termservice is dead.  The issue is completely random though intermittent we went a whole month between dec and jan with no issues and then started up again mid January.  We’ve had these issues since November.
