Sounds like progress, but I suspect it's a feature that needs Apple's attention. See if you have the Feedback Assistant app in this location. This is the app used by beta testers to send bug reports. It will send system reports etc that will aid Apple in fixing the problem along with your description and details of your problem.

If you don't have Feedback assistant, you might want to enroll in the public beta.

Beta testing is not for everyone. If you don't have a good backup strategy (Time Machine and clone) I suggest you have backups first. You'll get a new build approx once a week.
There is no Apple Public Beta forum to discuss and get help. MacRumors does have a place to get help but it's all volunteer. macOS High Sierra (10.13) | MacRumors Forums
