Can't submit Plugin update

Hi,

I tried to update my simple Plugin, which I originally added back in 2022. Unfortunately, I got an error which is blocking the update. I also noticed that when I click on the “Permissions” tab the dialog box closes right away. So I don’t know if there is missing something.
I also don’t use the E-Mail address anymore, which I added back in 2022. I have no access to it anymore. Instead, I would like to change to the one I use in my account.

Any idea what is going wrong?
Thanks, Danny
