Ah, thank you! I will try that warming method next feeding day. I just have a few more questions:

Could I try feeding again in just a few days instead of waiting a whole week? This is because of my concern about him not eating for too long, since it's been about a month.

Should I lower temps, like suggested in the first link that Vivi provided?

And lastly, should I try switching to a smaller enclosure/divide off his enclosure to make it smaller? Although, I am worried this might stress him out since he seems adjusted to the one he's currently in (in his hides all day, roams around at night for a little starting around 11 pm).

Thank you again, guys! All of this has been very helpful and I am re-evaluating all of my methods. Hopefully I can get my stubborn noodle to eat.
