Recent server 2022 APR2026 updates broke GPU

[UltimateInternet]

RDP and Hyper-V in extended modes do not work after windows client APR2026 updates.

Re-copied GPU drivers into the hyper-v successfully with same result.

Any ideas?

Use this for YEARS without issue until today on MULTIPLE SYSTEMS (only ones with the APR2026 updates on the hosts)

edit: after further investigation it is client related not server update related which causes GPU failure to start on rdp/hyperv

from an RDP client:
error code 0x11
The graphics display components in the remote session failed to start up.
