I noticed this issue, and thought it might be useful to point out that this is clearly a new compiler bug.
From the first fatal error in the full log: NSGraphicsContext.m: In function ‘+[NSGraphicsContext(Private) _initializeMethodTable]’: NSGraphicsContext.m:532:42: error: expected ‘)’ before ‘::’ token 532 | GET_IMP(@selector(DPScurrentcmykcolor::::)); | ~ ^~ We can see that the compiler has 'recognised' a '::' token, but inside @selector(...) each colon mark the point at which an argument would be inserted into a method call, so the compiler cannot legally tokenise pairs of colons as a single token in that context.
