I can reproduce the crash. I think this is not a bug in the plot addon per
se but a change in behavior after migration to Qt 6.
It cannot display any dialog box during paint event but an J error happened
|length error: frames 3 and 4 are not conformable: pdf_text
|   pos=.pos    -"1(-:len),.0

It crashed when trying display this error in a dialog box.
