I experienced the same behaviour. In my case I had temporarily continued to work on a Yocto environment after a few years of pausing. No suggestion out there helped, and the answer above is to specific.

I got rid of the problem after installing python-3.9.0 using pyenv. Meanwhile, after having created a new, fresh Yocto environment, it works well with ubuntu 22.4 standard python-3.10. using the new environment while python was still at 3.9.0 resulted in this problem: Git issue Bitbake gets stuck at do_fetch?

It shows that the python version can very well affect the process, without getting appropriate debug information via bitbake -D.
