Thanks for opening this issue.

Might some antivirus program lock the file until scanning has been finished?

@sentangle are you using an antivirus tool, which might block the file?

I think we could probably just change the deletion of that temp file to a best effort case. If it could be deleted, that's fine otherwise it will be left in there and overwritten during the next build.

[leaanthony]

Weird this seems to be happening only on Windows. I agree with just best effort delete. I'm not 100% sure it will be overwritten though if it's locked. Let's see 👍
