Weird spazzy textures in NGHL/HL

So, I just got HL1 today with experience after BM but just recently after I relogged onto my office complex save, the textures seemed to bug out every step I took.

I’ve already tried changing it to software, which crashes everytime, also re-validated and uninstalled multiple times. I’m all out of ideas, help would be appreciated

Is only that save is corrupted or it happens no matter what you do?

Every save, every server.

I would either try disabling your antivirus or reinstalling the game to a different folder.
