For some reason I can't download battle.net anymore (STays at 25%)

Been playing for wow for about 6 years and I’ve really started to enjoy classic Wow! But for some reason I got logged out and I cant even download battle.net anymore! Super frustrating. Ill attach a screenshot of what it says when I try to redownload battle.net.

Thanks for any help you can provide.

In case any of their advice helps:-

In most cases, ending all of the “agent” tasks related to Battle.net in the “details” tab of taskmanager, then restarting the client can fix issues.

Otherwise consider uninstalling and re-installing the client.
