slowdown of performance with last few updates

Just wondering if others have noticed a significant slowdown and hanging with the lasted updates.
for instance now when I heal it takes ages for photolab6 to redraw picture and heal area. it used to be a lot faster. also browsing through images on full screen on 134 inch laptop it takes a while for the automatic lens corrections to be included - even when the preview have been adjusted.
I am running latest version of PhotoLab 6 on my MacBook Pro with M1 processor and 16gb ram
any suggestions would be appreciated.
many thanks
