Save certificate as... broken in RDM 2026.2

Hi,

Since I've upgraded to 2026.2 I can't save my certificates from RDM anymore.

When I click on "Save certificate as..." and try to choose the file I want to save the certificate to I've got an error from the explorer saying the file doesn't exist. Of course the file doesn't exist yet because it's the whole point to export a new file.

Kind regards
