Hi,
Please try below troubleshooting steps first.
- Restart the remote desktop service and monitor to see if the issue will happen again.
- Disable the policy on the server "computer configuration->windows settings->security settings->local policies->security options->"system cryptography: USe FIPS compliant algorithms for encryption, hashing, and signning". Check if issue persists.
- Set the RDP security layer to "RDP Security Layer". Check if issue persists.
Thanks,
