Hotend pops and filament stops

[Falcon00]

Hi all.
Very new to 3D printing even though I have had my Ender 3 for a year now, haven't done a lot of prints. I am using PLA and have had this filament roll for about almost as long as I've owned my printer. I understand that filament can absorb moisture from the air.
Would this explain the strange behavior from my hot end or do I have some other problem(s) present?
Cheers
