I had similar problem with Intelij IDEA Ultimate, I solved it by installing Early Access Preview(with bundled 11 runtime, not sure if matters), it looks like they already testing it on Catalina. I don't know how much Android Studio beta is behind EAP in regard of IDE version but I would try.
I checked your's error log, it states exactly the same problem I'm having now with stable version.
Code:
Exception Type: EXC_BAD_ACCESS (SIGABRT)
Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000000
Exception Note: EXC_CORPSE_NOTIFY
