Unable to play video's for any of the courses

Hi Team,
I’m unable to play any videos of any course. The issue is stopping me to utilize my AI subscription. Can the concerned team please help

Did you try logging out and logging back in again? Or in an Incognito window?

You can also try clearing browser cookies or site-specific data.

Yeah, tried everything possible. checked on 4 browsers(Chrome, Edge, Opera and firefox w/ latest versions). Cleared cache and cookies, disabled all extensions, incognito but still persist
