it seems a problem with loading cygiconv-2.dll

--- Process 3080 loaded C:\cygwin64\bin\cygiconv-2.dll at 0000000001130000
--- Process 3080 unloaded DLL at 0000000001130000
--- Process 3080 loaded C:\cygwin64\bin\cygiconv-2.dll at 0000000001130000
--- Process 3080, exception c0000005 at 00000000014f5075

but the address fault seems in cygwin1.dll

--- Process 3080 loaded C:\cygwin64\bin\cygwin1.dll at 00000000014f0000

what version is installed ?

Can you try to reinstall it ?

$ cygcheck -f /usr/bin/cygiconv-2.dll
libiconv2-1.14-3
