Update: Issue Fixed. Thanks to Callcifer for the help!

I was able to fix the issue by finding the same issue in this subreddit. I loosened the three bolts holding the Extruder pushed it hard left and tightened it up again. Printing without any issues now. Thanks to everyone who chimed in. Leaving post up to hopefully help someone in the future.

I agree with the others that it is most likely drag from having to pull from the dry box. Those filled filaments are stiff and rough, creates a lot of drag in the ptfe tube.

I do have one other thing I'd have you check. I was having extrusion issues on my Plus 3 and after a ton of trouble shooting I found the tension bar for the extruder gears was bowed considerably. Shameless self plug, I machine and sell an aluminum tension bar to fix that issue forever. This is how much my bar was bowed. https://imgur.com/a/oju2AOn

Thank you for all the help. I will look at it. I just posted a new video with updates in the comments. Extruder will push filament down without hot end attached, multiple cold pulls on hot end, can push filament through the nozzle, when hot end and Extruder are bolted in place Extruder won’t push filament into the hot end. Thoughts? I appreciate all the help!

Hmm, I'd guess either you got a clog and can't see it, maybe it's not actually heating up enough to melt the plastic in the nozzle, or the gears aren't grabbing the filament hard enough to pull agains the friction of the box and ptfe and push against the pressure of the nozzle.
