SC2 Crashing on MacOS Catalina with Radeon Graphics

Still crashing the game and my imac they wanted a new thread if you have a Radeon Pro 575 4 GB graphics. Sometimes the game works (rarely) and it will either crash the game or my imac. I have tried everything they have suggested but nothing works. Been going on sense the os upgrade to catalina. Some options they suggest i do not have that option. I even uninstalled and reinstalled still nothing.
