Hyper V role enabling issue in server 2019 DC edition

Copper Contributor
Hello colleagues,

I am facing issue while enabling hyper V role in server 2019 dc edition. / Dell physical hardware.

Error: the referenced assembly could not be found. Error: 0x80073701

In Dism logs, same error. Status_sxs_assembly missing #

I have tried to enable the role via Dism/ poweshell - still the same error.
Also while enabling role I have given the path to sxs folder, still the same error.

Have run SFC/ scannow- all good
Tried to restore via Dism - all good.
Single launguae pack installed in server.

Please suggest.

0x80073701 = ERROR_SXS_ASSEMBLY_MISSING which means there are some system files are missing, which caused the update installation failure. You can also try a repair install by running setup.exe from the root of the install.

I wouldn't hold much hope for this, better time may be spent standing up a new one, patch it fully and migrate the roles or applications over to it.
