New Mute / Solo bug in Cubase 15?

I noticed, when I go solo and then press solo again to go back to normal (all tracks unmuted), some tracks are not playing although they are not muted. I have to press mute again twice and then they start playing. This is new since Cuabse 15. (And it is not like the mute/solo problems with Cubase14 - those where different and have been fixed.) Happens not all the time, but I noticed it several time within the last weeks. Anyone else had this, too?

Hi,

Do you know a way, how to replicate this issue? Does it happen in all projects? Are these tracks somehow special?
