channel strip EQ mutes channels

There’s a strange issue in 10.5 which happens randomly when opening saved projects.
Activated channel strip EQ on groups might cause them to be muted when engaged, the only solution is to disable the eq or duplicate the group and re-route everything again, and the same eq will work fine.
And on some audio tracks activated eq might mute just the left channel, same solution, disabling the eq or duplicating the track to fix it.

What happens, if you click to the Deactivate All Mute States (even though it’s not enabled) once this happens? Does it help?

Do you have any project, where you can clearly (or at least more often) reproduce it, please?
