Help: Tone Knob Shaft – Unstable/Wobbly.

Recently, I’ve decided to restore my beloved guitar (after the silly mods based on the internet). My dumb a** self accidentally pulled the knob away and a bit too much of a force. Now the guitar’s knob which is still attached, can be pulled loosely, leaving the gap away a little bit from the wood. However, the cover is still in tact with the metal shaft itself. And whenever I turn it, it has a bit of resistance as well. Does this mean it’s a major repair and will this affect my guitar in the future as well?

Thanks for your help!
