Playlist only plays first 100 songs

I have a playlist that has ~400 songs in it, which I listen to shuffle on the daily, however recently it has only been playing the first 100 songs during shuffle AND if I try to force it to play a song past the first 100 songs it provides the error message

Heading "Not available on the web"

Info "You can listen to this on the web"

It works just fine on my phone, but on my pc, nothing

I use Opera GX if thats helpful at all.

(Its not a MacBook pro btw, I just cant find a non-apple product, i have a GeForce tower)
