Hi,
Are you able to install other roles? If this issue only occur on installing WSUS role, please follow the steps below to re-install the WSUS server:
- Romove WSUS, IIS roles and WID feature.
- Rename Update Services, inetpub, inetsrv, WID folders.
- Re-install the WSUS role.
If this error occurs on installing every roles, the system may be broken, please try to inplace upgrade to recover the system:

If it still doesn't work, re-building the OS may be a simpler way to fix this issue.
Best Regards.
