rdVH deployment FAIL

I had 3 VM collections, were working all right! All of a sudden, If I try to create another Virtual collection i get this error with empty reason for failure. (with any Windows version)

If I choose the option to create Profile disks it says it failed to create Profile disks, but when I go in the collection to reconfigure it a red error appears saying there are no rdVH or rdSH. ...but the VMs appear when I create a collection.

The collection is created with no machines in it. If I try to add a machine I get failure again and similar event log.

I have Sql HA, but I don't notice any errors there.

The connection Brokers services are usually crashing, and I need start them manually before I can access the RD server manager... maybe for another ticket.

And if I try to restart the rdVH service on the hyperv host the service fails to restart. A reboot will fix. The following error appears for every VM.

--------

Failed to set value of the '0x80070002' Data Exchange integration service item for virtual machine 'tenpro-n': 쾴쮎翶 (The system cannot find the file specified.) (Virtual machine ID 椏d)

---------

If I destroy the collection, remove and reinsert the server,  I see errors on Server manager:
