Udemy vids are not playing

[goatedpenguin]

Sooooo I basically just started using Thorium and she is fast my only gripe about it is that when I am on Udemy the player just gives me a black screen and does not play anything. Can this be a codec issue or some other thing going on? One thing to note is that I use localCDN and Ublock Origin, all the settings are stock in both of them except the rules that LocalCDN had generated for Ublock Origin. I disabled both and it still does not work however, strangely I have all the same extensions on Firefox and it works fine. I suspect this may be some sort of issue with chromium based browsers or maybe just Thorium itself? Thanks in advance(all the extensions I use are down below):
