[HL2] Workshop doesn't load player model physics

[Hds46]

I have an addon uploaded to Half-Life 2's steam workshop which changes player.mdl
But it doesn't load model's physics despite .phy file being present in the addon.
When installed manually it spawns player ragdoll but when installed from workshop it just spawns t posing player model without physics.
This is console message when it tries to spawn ragdoll but can't
*** ERROR: C_ServerRagdoll::InitModel: models/player.mdl missing vcollide data ***

Was it this one? https://steamcommunity.com/sharedfiles/filedetails/?id=3373109095

I don't know if the player ragdoll is spawned if you use the "setmodel" CMD to change to something other than the HL1-based Gordon placeholder such as Alyx or Barney, but I might assume the PHY for "player.mdl" isn't working as it should.
