500 error upon attempt to create API token for R2

I am unable to create a Read & Write API Token to a specific bucket.
Once I fill out the form I receive server error 500.
API token could not be created. Please try again.

Moreover, I don’t understand why do I need to seek for community help not Cloudflare support if their endpoint is faulty and Support AI said only “I don’t know”?

Navigate to your api tokens (top right person icon → my profile → API Tokens), or magic link: https://dash.cloudflare.com/profile/api-tokens
Do you have 50? If so, you hit the limit and will need to delete some. That page sadly doesn’t tell you that.

Hello. I did it but I’ve got only 1 token in place for another R2, unrelated. This is the second one I need.
