Having the same issue with flutter as Bleik_Urrego

I'm having the same issue. Signing the agreements temporarily solved it but I've bene having the issue on and off (mostly on) ever since.

I'm having this issue and while signing the new agreements temporarily fixed it, I still have this issue quite often. It works roughly 50% of the time. Sometimes restarting Xcode once fixes it, other times (like right now) nothing seems to fix it... And then eventually it ends up working. This time around I actually managed to upload it but there was a bug with the notarization, and I can't seem to upload it a second time.
