Problem with attach files to email gmail. (docx-files)

Version 1.37.109 Chromium: 100.0.4896.60 (Official Build) (64-bit)
kubuntu 20.04.

when downloading docs. files from email it download it as a zip file, then when you have unzip it the downloaded docs-files is not in the zipped file. Same when trying to attach docx to send as a mail it will say this file has 0 bit and can not be attached, but in Firefox attach and download docx files works with o problem.

there was a simler problem about a year ago but that topic was no answer in if that was fixed or not.
