Download as ZIP in "My Data" no more working in Brave and FireFox

Hi Support,

I would like to download the images of my last run, but the Download in "My Data" is no more working at all. Below is the captured run for the download.

After clicking "download data" that windows opens - with the information “Download as ZIP works in every browser.

After clicking "Start Download" all files were compressed.

But now window opens to select the download folder on my computer. Tested with Brave browser.

The FireFox-Browser has another behabvior. The below error message pops up.

In the Edge-browser it works - the download notification is in German language.

Around one week ago it worked in Brave-browser.

Many Greetings

Peter
