You can also access YouTube channels with handles without the @ but this bug fix does not include that. For eg https://www.youtube.com/@CharlieSolis works but https://www.youtube.com/CharlieSolis does not open up within Newpipe. But they both load properly on a web browser.

Should I open up a new issue? New to using github. Thanks in advance.
