2021 custom palette crashes

Painter 2021 (still in trial mode) installed fine and working well.

BUT,

still have same issue that occurred with 2020...

Often, not every time, when shift drag a brush (or other item) to create a new custom palette, sometimes works...

I have about a 20% success rate.

try to move item in palette or add more...and BOOM..Painter is dead...responds to nothing, is hung with 12% cpu usage, won't close in any way except to use task manager to kill it...

and of course all is lost regarding the palette and anything not saved immediately before.

I give up trying to make custom palettes.

I reported this same thing for 2020. I am VERY careful with holding keys and in correct order...still get many crashes

Call me frustrated and Corel not having looked at this issue???
