Stuck in Grant Access to Source Code

When I first create workflow, I want to connect my source code to bitbucket server, but I was stuck in connecting step, just look the images below.

I keep getting 500 error.

How can I connect to Github or Gitlab?

I can't find a way to switch or change, please help me, thank you.

I also send a feedback. FB9782531 (Xcode Cloud Stuck in Grant Access to Source Code Step when first create workflow)
