All Half Life 2 models are in T Pose

Hey, First of I tried posting this in Help and Support but I didn’t get much luck so sorry for double posting. Anyway recently I’ve noticed that all half life 2 models appear in “T Pose” which is really annoying, here is a picture of what I mean.(This is for players and NPCs)

Also, unsure if this is related to the T Pose problem but when players die they suddenly appear as two ragdolls on the floor.

Thanks for reading, hope I can find the solution to this.

This or this or this should fix your issue.

I already found them and none of them worked for me.
