.pdf is created, but no .svg -> no import to Inkscape

[mharmel]

using Inkscape 1.0.2, running on Windows 10 64 bit

When I try to convert a selected textbox to LaTeXed results,
the .pdf "writetex.pdf" is created in C:/Users/username/AppData/Local/Temp/writetex-**********/writetex.pdf.

But I get an Error in Inkscape, because it was not converted to a .svg in the same directory:
" OSError: Error reading file 'C:\Users\mharmel\AppData\Local\Temp\writetex-8as680uu\writetex.svg': failed to load external entity "file:/C:/Users/username/AppData/Local/Temp/writetex-8as680uu/writetex.svg" "

The textbox is not replaced by a LaTeX render.

I also get quite a few DeprecationWarnings.
The error log Inkscape is showing is attached.

Thanks for the feedback. This is expected. Because Inkscape 1.0 has some incompatible changes in the extension API, they are not implemented in this plugin yet. Please use WriteTeX for now, it has a version for Inkscape 1.0+.
