uvx ocrmypdf tells me file not found

I’m on Windows 11. I’m trying to OCR this PDF file with uvx ocrmypdf, but I get many “The system cannot find the file specified” errors.

The output file appears to be fine and OCRed.

Why I’m getting all these errors?

uvx ocrmypdf --language ita --force-ocr 19940809_185_SO_113.pdf ocred.pdf

Possible reasons for this include:
--force-ocr (or --mode force) was issued, causing
transcoding.
The optional dependency 'jbig2' was not found, so some
image optimizations could not be attempted.
The optional dependency 'pngquant' was not found, so some
image optimizations could not be attempted.
