mac restart

According to my information the current version of Paragon NTFS is 15.5.143. If you are running an older version, then it may not be compatible with Catalina. This could cause the problem you are having. Unfortunately, the watchdog error was associated with the WindowServer process which doesn't help identify the true cause.

The watchdog process monitors something to make sure it's running and hasn't crashed. If it panics, then some process isn't responding in a timely manner or has crashed.

Try booting into safe mode and see if that stops the problem. If it does, then you may have an extension problem or other system related issue.
