Transmission issues

Hey guys, new here on the forum (but have used it for years to fix my shit). Recently the trucks started making a noise that sounds like a bearing racing when I press in the clutch, but normally only does it when I’m putting it into first gear.
It also has become increasingly difficult to get into first gear. Wondering if it’s the throw out bearing or the pilot bearing. The clutch was replaced 50k miles ago and isn’t slipping at all. Any suggestions or help would be greatly appreciated!

 

Try double clutching when you go in first, is it any better?

how’s it run through the gears with the engine off
