Meaning of this exception

Hi,

I sometimes get this exception when I compile. But, if I just compile again (or in the next 2/3 re-compiles), compilation is successful. What is happening here? Also, what does this warning mean - it’s true that the libs present in …local/lib are built for 10.15, however, what does “than being linked (10.13)” mean?



...
CompilerResultsLog: ld: warning: object file (/Users/xxxx/.local/lib/libcrypto.a(v3_prn.c.o)) was built for newer macOS version (10.15) than being linked (10.13)

Thanks!

Well. the sharing path violation seems to happen when I compile and change my active window to visual code (visual code and unreal are trying to access the same folder).

Still not sure of why the files are linked against 10.13.
