I was trying to put my game to test flight. I would test features like ads and in-app-purchases, then put on the Appstore(release). The game already works on Ipad. For test flight, the "automatically manage signing" option was enabled. Then I pressed the "archive" button. Built succeeded. Then I clicked the distribute button. That time, I had an error. "Upload failed, Invalid signature, App is not properly signed". I researched, and found special characters in name, team name and address can make errors. My name, address and team name have special characters(turkish). If it will be resolved, I want to re-write(fix) my name, team name and address. I already tried to change my name, team name and address from apple developer website but failed. They are asking a document of my identity of my new name but I didn't changed my name and address. Overall, there aren't any other facts that cause this issue as I know. If I send my current, unchanged identity and home address, could they allow to change(fix) them?

Error : Invalid Binary rejection email indicating a corrupted code signature was detected. Explanation : Invalid Signature - Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose "Clean All" in Xcode, delete the "build" directory in the Finder, and rebuild your release target.

You are correct. Special non-ascii characters in your team name or any of the files in your project can cause problems with code signing.

Please contact Apple Developer Programs support for help changing your team name. You can contact them using the options displayed on this page ~ https://developer.apple.com/contact/topic/select

I changed my name, I still get the same error. My team name also changed. Do I need to wait for a while to the error to be resolved? And my address also include special Turkish characters. Do I need to change that too? I said, but they just changed my name not my address.

Here they say :

As requested, your name has been updated to "Kaan Selcuk Karaboce". Although the change will be reflected immediately in your Apple Developer account, it may take up to two weeks for the change to appear on your contracts in App Store Connect. Also note that if you previously submitted tax forms within App Store Connect, these forms will continue to show the old name. You can disregard this information as tax forms are static and do not reflect name changes.

Also they said, my name in the certificates won't change. Do I need to change it?

Here they say :

Please note that updating the name on your developer account does not alter the name as it appears on the certificate. Certificates are signed with the name that was originally used to create the Apple Account. Apple Accounts are non-transferable.

Yes, I believe special characters in both the address and the name can cause problems. I do not know of any issues with special characters in certificate names.
