I’ve investigated further and only explanation I can see is that this is a CreateFileW with GENERIC_WRITE and OPEN_EXISTING and there is an unimplemented path in uba for that in combination with “output files”.. “.exe” is an tracked as an output file from the linker.
I still don’t understand why you get this while I have never seen this with the 100s of devs using this daily.. but I will add code to cover this case. Only thing that sucks is that when you link remotely your path will need to download the old .exe file just to then overwrite it
