I use VLC and watch at double speed for most things. Honestly I just skip movies and TV mostly but the stuff I do watch is at double speed for most things, sometimes 1.5x because people look weird moving fast when they are doing action scenes.
Now podcasts and audio books on the other hand are very amenable to increased speeds. The narrator increasing the speed just increases the rate of intake, the mental simulation is still at a reasonable speed, just less time waiting.
You could try heat cycling it. Heating the screw, not hot but like 60-70°C, then bringing it down to quite cold, say around -15°C, should first push everything outwards then compress the screw. Once that is done a little bit of silicone lube should get through the tiny gaps and help everything move. Just make sure the lube is compatible with your plastics, some plastics are harmed by compounds in lubes.
Past that, try to find out what the cheapest part would be to replace if needed. Make sure to load that part most in opening it up so if it breaks you can replace the cheapest part.
