Update 2022.0.1 (v9)

I fixed and redone several things regarding new sounds. There was a critical bug, which was fixed in the afternoon, but in the meantime, I started working on new icons (new implementation, which was cleaner + more performance), but I was in the middle of that at that time. For that reason, I have released another small patch with extra error checks. All should be OK now, sorry for any inconviniences!
