Had my first Cubase Crash on initial 11 testing using the C11 demo. If i hit the stop button on the playing project an instant crash occurred.
Didn’t happen in Mojave 32bit but only Catalina 64bit. After some digging for me it appeared to be linked to Cubase finding some residual 32bit code id forgotten about.
Mine was in the Tools for MR and FW driver end. (Id just updated my interface from an MR816CSX to an AX4R but forgotten to clean out the underlying code for the old interface). After running the uninstaller from the Tools Extension my crash issue ceased.
