Well, using a search machine to find an error code interpretation is not necesdarily sensible. The number -1073741819 (a bit different) can also represented as 0xC0000005 assuming thar the program use a 32 bit number range.
That error code is a composition of the error number (5: access denied) and the error class. 0xC0000000 stands for generic error.
So all you get from the code is "access denied". The actual error can only be found if Lilypond issues the function that returned this code. Do you think that the complete error message could be shared?
I also wonder why the error codes are displayed as decimal numbers. Wouldn't it improve tge user experience if the code is readable?
