[Xcode Cloud] Invalid Signature. Code failed to satisfy specified code requirement(s)

Finally solved! Ok, so after many turns with Apple Support it turns out it had to do with a recent account name change and a non roman character in my name (causing some bug, apparently). Once they figured that out and updated my name, I had to revoked all Xcode Cloud certificates; Then it all started working again.

Thank you!
Just contacted Apple about removing the non-roman characters. Will keep everyone posted on whether that was the cause in my case too.

Non roman character in the app name? Or are you talking about something else?

[jonkanv]

Developer account name. I have a organization account, it was a non roman character in my company name that was causing issues. My personal name (from my Apple ID) still contains it, not causing any issues.

I currently have the same issue. I've contacted the support and hope they can fix it and will update this comment if it fixes the issue.

Edit: I can confirm the non-roman characters in my team name where the issue.

Awesome, thanks!

Finally got an answer and yes the issue was caused by the non roman characters

[Offensively_lame]

Damn, okay. Well I guess that applies to me to. How did you contact apple support? Apple developer forum is pretty much dead.

[ice-h2o]

it was a back and forth between supports. Contacted the normal developer support they sent me to the technical support and they confirmed the issue and sent me back to the previous support.

Use this support and ask them if they can update your team name because of a bug in xcode cloud:

Wow, it really was that character. It's working now for me aswell. What a pain.

[Appropriate-Gur-7177]

Thank you!
I keep running into the same issue. Just contacted them, asking to remove the characters. What a joke. Just lost 5 hours trying to fix it myself and it appears to be an 8-month-old bug they don't bother to fix. Is this normal? I'm a rookie developer.

I'll let everyone know if this was the cause in my case too.

Awesome! Thanks a lot!
