Provide a description that is worded well enough to be understood

Some channels on YouTube redirects to old & unsupported links (i.e. https://youtube.com/username instead of https://youtube.com/@username). This bug is not specific to YT-DLP, in fact, opening a bugged YouTube channel directly from the link won't work and show the 404 Not Found error page because you got redirected to the wrong page. However, by searching on YouTube the channel name and clicking the the person's name, its the same exact URL but you are able to load the page without getting redirected. Seems really weird, IDK why it happens. I am not using any credentials inside YT-DLP, and the bug happens both in Brave browser while logged in and Brave browser while not logged in (inside a private window).

Example URL (won't work if you click on it, but search "ZimnyteGD" on YouTube and click on the profile to get the actual user page without the weird bug): https://www.youtube.com/@ZimnyteGD The bug also happens when giving a specific tab, i.e. https://www.youtube.com/@ZimnyteGD**/videos**

Provide verbose output that clearly demonstrates the problem

[X] Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
[ ] If using API, add 'verbose': True to YoutubeDL params instead
[X] Copy the WHOLE output (starting with [debug] Command-line config) and insert it below

Yeah, obviously, but if they don't fix it, is there might be a patch for it in the future ?
