My 2018 MacBook Pro is sometimes suffering from 'sticky' volume control.
When I am interacting with the volume controls on the Touch Bar for a longer period of time, the volume control gets stuck sometimes. The sound is then automatically, continuously being muted or (with a bit of bad luck) set to full volume. During this time, the adjustment popup remains constantly visible.
Only when I go mach five on the Touch bar and press all the volume buttons in random order (haven't been able to find a pattern), the OS surrenders and I regain control over the volume.
It usually occurs once or twice every week. It also occurred on a clean install, so third-party apps acting strange is out of the question.
Is this a known problem? Is there a permanent solution?

First of all, restart your MacBookPro
If this doesn't work than try reinstalling macOS by booting into recovery mode by pressing command+r while startup, select "reinstall macOS". I recommend doing a backup first even you won't loose any of your files and settings.
