It wasn't giving an error message, but it was just lingering as if it wanted to launch. I contacted Apple and the guy was extremely nice. He did a screen share and was trying to help me for an hour and still nothing. So, almost 16 hours now and I was literally about to give up until I was thinking to just start with an older download but Mac there is no 32 download. So, I installed Firestorm 6.0.2 (56680) Animesh Release, which worked surprisingly ... Now, I want to slowly upgrade back to the Firestorm 6.3.2 (58052) Bakes On Mesh Release, but a little nervous that it won't respond. What you think? My laptop is the latest MacBook Pro 2019 16" if that helps and it's running Catalina latest update 10.15.4
