notarytool not completing

I'm trying to sign my application but the build times out after 90 minutes waiting for notarytool to return. This seems to be getting worse and worse.

I have now updated the timeout to 10hours, to see if I can get a response at all.

Something is very wrong with the tool.

This was working fine up until about the 28th March 2026.
