Hey everyone,
The issue has been fixed.
To be honest, there was no issue on the server or hypervisor.
Apparently the issue was due to my wireless devices.
RDP and Remote management connections were stalled due to a bug in my Wifi6 Mesh system.
Connecting with the same device wired worked perfectly.
Happy that it was as easy as that, unhappy with the time I lost with this.
Thanks for everyone with the tips.
