I’ve experienced this too, mainly after critiquing a recording and then attempting to record again, while trying to keep in mind all the points I used to ‘fix’ the mistakes. I think it’s a matter of changing hats so to speak.
First the solution should involve isolating the specific tricky bits and practicing them enough, at a slow enough pace so you do have time to think, in order to put the fixes into permanent memory without having to ‘think’ about them.
Next I think practicing ‘hat switching’ is in order, to get that ability under your control. So first you think and practice, as above. But then you stop and do some centering (where you -can- imagine all those details ahead of playing) and mind-emptying. Followed by creating music (ie not practicing, just playing with a still mind). Even if you can only do that latter for a couple of seconds at first, you have practiced the ‘hat switching’. Aim to extend the amount of time you can create music without interrupting yourself. If you find yourself thinking when you’re supposed to be in ‘playing mode’ then you would remind yourself which hat you are wearing. Sometimes I’ve just stopped and sat there holding my flute till I stopped thinking. Change back and forth between the hats, always taking time to empty your mind before creating music.
I observe things to stay in the moment when playing. Hearing the sounds, feeling the pulse of the music, feeling the vibrations underneath my fingers, observing unnecessary tension so it releases. When I just can’t clear my mind and take off the ‘coach’ hat, I take a break.
I’m no expert here, I’m still doing the course myself, but this is something I work on and use with my students too. Hope it helps!
