I found that BTT "disappears" (probably crashes) on M1 Mac Mini. It happens really "unnoticeable" or spontaneously. I can't tell when it is crashed and from time to time I found the app disappeared and have to restart it. There are no report crash window or error message - it just silently disappeared. And besides this, there are no other issue at all.
BTT version: 2.426 (785)
MacOS version: 11.0.1
Since I'm using the latest version that my license still works, I'm not sure if this bug would be fixed for us who owns the earlier license.
