Thank you for attempting to reproduce the issue, Basj. Debugging an issue like this can be challenging. Even though you cannot reproduce it, I'm hoping we can find the issue if we work together.
I attempted a clean boot on several occasions and the freeze still happened. Unfortunately, it is not a guaranteed timing or action that causes the freeze. For example, I just woke this laptop from hibernation 6 hours after gaming for an hour this morning. The taskbar is not frozen at the moment.
The only guarantee I have is that Start11 is the culprit of the taskbar freezing. The problem does not occur when Start11 is uninstalled completely.
Back on November 8th, your colleague Neil Banfield mentioned this issue was a resource leak (reply #15 on this thread)
The issue has indeed been resolved. The earlier 2.x beta had a resource leak causing this to happen over time.
A similar leak was in 1.x and I believe the plan is to put the fix in an update for that once the dust has settled on the 2.0 release.
The issue is clearly not resolved since it is occurring for three different users. I'm happy to run a resource monitor or provide a memory dump if that will help, just provide instructions on how to provide the proper format.
