Try disable all the 3rd party software from the source list first.

I also suspect main culprit being cloudflare. That said you can't beat a fresh install after backing up all critical data, plus app settings. But not before trying in live mode.
Turn off - or if this shouldn't be enough delete - the listed Repo's and do a sudo apt update and then try it again.
i did all that , no way, i wish if there is anthor way to upgrade, it seem the upgrader app is not working with me
Remove the added repo’s. Brave and cloudflare.
there is a manual upgrade instead of using the upgrade tool???
What does that mean? Dod You have deleted the Repo's what are in blue in Your Comment?
No. Only save Your Data and make a fresh Install.
