I can no longer change weight of lines imported from AutoCad without them disappearing.  Does anyone know of a fix for this?  I'm on version 25.3.1

I just encountered a similar problem on a file with autocad elements. I was able to work around it by adjusting only one color at a time. Pick a line, chose Select > Same > Stroke Color. When I did it this way, I was able to change the stroke weights without losing the color and having them disappear.

Thank you for the workaround suggestion.  Hopefully, an future update can restore how easy it use be to change these line weights.

It may be related to a bug that was introduced in the latest version of Illustrator.

Can you share a sample file?
