Librewolf fails to open attachment - file not found

General system Applications
1

I am using Librewolf flatpak version 151.0.4-1 and proton mail via this browser. When I click the download arrow on a spreadsheet attachment I am offered the option to open or save. I choose open and then get the error /run/1000/user/doc/110d1fa8/Driver Manifest Report for 599 - Scorpii Enterprises Inc (Paul)-4.xlsx does not exist (from libreoffice-calc). However when I go to that directory it is there

-rw-r–r-- 1 scorpiipc scorpiipc 8507 Jun 17 23:28 ‘Driver Manifest Report for 599 - Scorpii Enterprises Inc (Paul).xlsx’

This does not happen with the same flatpak version on my mint laptop. It opens just fine.

Update - it works properly in the eos native Firefox

Is libreoffice a flatpak or native?

As noted in original post Flatpak version 151.0.4-1

That is librewolf, isn’t it. I was asking about libreoffice.
