I believe this has been resolved by @KubaO => Uninstalling your wxMaxima and installing the one from https://wolfgang.dautermann.at/maxima/nightlybuild/ should resolve this problem, I hope...

Unfortunately I have the same behaviour with:

I don’t think I did anything to fix that one. I fixed a different bug that caused an assertion when selecting cells, but nothing to do with wxmx files.

Actually the problem is on wmx file. wxmx files works fine.

Hi,

I see a related behaviour when a heavily folded worsheet/notebook is converted from wxmx to wxm (in a plain wxm is delimited [wxMaxima: fold start ] ... [wxMaxima: fold end ] ). The file crash_test.wxm folded reaches %o61 but unfolded reaches %i763

Actually, in the case reported by me, an unhandled exception is triggered (https://sourceforge.net/p/maxima/mailman/maxima-discuss/thread/CAAftCjpx%2Bp0n0sqeChmWTDqGsGU54fLgZedKZR-u%2BPN83AVsyg%40mail.gmail.com/#msg48497303).

On my computer the current nightly build of wxMaxima restores the file as good as it can. The only thing is that the file is throughly broken: It claims the worksheet contains a folded section containing a folded section containing a folded section... => will have to debug the .wxm saving code.
