Can not create account in peertube. capcha not filled?

there is no capcha i have to fill, as i can see on the page. can you help me make an account?

This peertube instance seems to use a captcha plugin that is not correctly configured. My browser console displays the following error: hCaptcha plugin lacks a site key set to use hCaptcha. Falling back to normal registration.
If you are the instance administrator, you have to configure or remove the hCaptcha plugin. If you are not, try to contact the administrator, or choose another instance.
