Power Charges Not Generating After Swapping Corrupted Ring

Hey guys, I’m running into a weird issue. When I swap my corrupted ring for one with Rarity Found, I suddenly stop generating Power Charges and can no longer activate Charged Staff.
I’ve tested this with multiple different rings, and every time I remove the corrupted one, my Power Charges just stop accumulating. I’m not sure why this is happening—does anyone know what could be causing it?
Example of the swap I’m trying to make:

you probably have no other source of cold damage and that's why you cannot gain charges
The Intelligence bonus from the ring is likely required for all your support gems. Or is disabling another equipment item.
Do you have enough stats for all your skills?
To go along with what the others are saying, go to skills menu(G) and if either the top stats have red X/Y things or when you scroll down, skills have a red outline on the box in the top left, you're missing stats needed for skills/supports.
You can insert a cold infusion gem into herald of lightning for mapping, or the electrocute gem on tempest flurry (if thats what you play). The latter will lose you some dps but work on single target. I switched from crescendo to this and honestly dont even notice the dps loss.. Think the gem is called conductivity?
It's likely the cold damage
