I'm having a related but slightly different error. Upgraded to Catalina, upgraded Steam and downloaded the new patch. When I run the patch install I'm getting this - Binary already contains a load command for that dylib. Continue anyway? [y/n] If I hit yes, I eventually get this - It doesn't seem like there is enough empty space. Continue anyway? [y/n] If I hit yes again, it completes install but when I run RS from Steam it immediately fails and the error log gives this - Exception Type: EXC_BAD_ACCESS (SIGSEGV)Exception Codes: KERN_INVALID_ADDRESS at 0x000000012ae65b0dException Note: EXC_CORPSE_NOTIFY Any ideas?
