trace bitmap box dialog crash block

[SUMATORIO]

Hi every one:
I'm using 92.2 version of Inkscape in Windows 10. My PC has Intel i7-6500u CPU 2.5 GHz Memory 12GB

After I trace an image, in my case a grunge texture, that have many paths, when I use the trace a second time again the elements of the dialog's box disappear. I need to close Inkscape and start again.

In my example, grunge texture, last a lot to finish the trace, because there are a lot of paths. It expends a lot of memory. It do it well but for a new trace, the elements dialog's box disappear.

I apologize for my English.

Thanks in advance

Regards.
