Major lag when using Logic Pro Flex Pitch

I am running a 2023 Mac mini M2pro chip 16GB.

everything (OS and Logic is up to date.

It is a quit big live recording of 28 channels of 1,5 hour music.

To move a note up or down in Flex Pitch mode it takes at least 2 seconds to complete that action.

When I moved the note it will go up or down but then the beachball comes in for 2-3 seconds.

More people having this issue??

Apple? is this still a bug in logic 11.1

Please help
