I want to submit a bug, but I can't complete the registration.

Now I want to report a bug, but I click the anti-bug button at the top to get a link to the registration screen, which tells me that the user name contains extra characters and cannot complete the registration, and I don’t know where to change the user name, so now I am stuck in an endless loop. I tried to change the user name and name in the user interface of the forum paper, but this did not work. I still can’t complete the registration.

let’s try to go to https://projects.blender.org/ and sign up there via Blender ID. What’s your Blender ID username?
