Have you ever been working on an access policy in Cisco Firepower Management Center and then seen the following error pop up when you opened or saved a policy:
An internal error is preventing the system from validating this policy. If the policy is misconfigured, deploying configuration changes may fail or your changes may not work as expected. Contact Support for assistance.

My web interface then showed that system services were restarting when I tried FMC again. As soon as that wrapped up, I went right back in to try to open that same access policy I was trying before. It opened….and I never received the error. Worked like a charm!
As always, this helped me, but things may be different for you. Consult TAC as needed. In this case, the command executed and resolved the issue with no service interruptions for any of my firewalls. Consider it similar to rebooting your FMC, your firewalls continue to function. Took me a bit to find this bug for some reason, so hopefully this post can help someone in the future!
