Hello
You can try to check if you have the following policy enabled:
Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Audit: Shut down system immediately if unable to log security audits
If so, please consider disabling the policy.
You can also clear log, increase the maximum log size or let it overwrite older entries. Refer to: Start --> Run --> EVENTVWR.MSC --> Right click Security log, go to Properties. Then, you can clear log, increase maximum log size or choose “Overwrite events as needed (oldest events first).
Best Regards,
Wesley Li
