Rhino 7 - Linetype CRASH

Hello there from Seligenstadt Germany,
i have the problem, that i can´t edit any of my linetypes in Rhino 7. I am also not able to create any new lines and save them. if i open a rhino 6 File with several types of lines in Rh7, they are shown right, but i can not change them. In Rhino 6 there are no problems.

I am thankful for any help.

Hi Justus -

As you can see from the other replies in this thread, that issue was fixed in Rhino 7.4.
