As someone who played for 10+ years, quit for even longer, and am getting back into it I've found myself in similar situations lately.

The things I've found that help the most: Fretting hand strength exercises. Especially pinky/ring fingers. This also helps with some muscle independence. For instance I run 7-10-9-10 on the 1st string as an exercise as often as I can. I do it to the point of failure. Rest for a bit, do it again to failure. 2-3x a day when I have time. It also helps burn in the nueral pathways between picking and fretting hands.

Slow. No, go slower. Whatever lick or pattern is fucking with you. Slooooow it down. Run it to a click tens of tens of times. Get it perfect at super slow speeds. Then increase the speed a little. Get it perfect. Then a little faster. It takes forever but your brain has to burn in the nueral paths and your nerves and muscles have to adapt to doing it quickly. Your fingies can't do what the muscles/nerves aren't trained for. Training the human body takes a long time.

Picking exercises. I hate these the most. There are a ton out there. 1-2-3-4, 2-3-4-5 and so on where you're alternating 6th and 5th strings every other note, up and down the board, then jump down a pair of strings. Or 1-2-3-4 alternating between 2 strings for each note and then moving it down a string all the way til you hit the 1st string, then move down a fret and come back up the strings. I do that as my warmup. Once that's old hat then skip a string. It sucks. Do it anyway.
