Cannot open remote files mounted with rclone

I have a remote file system mounted with rclone on my Fedora 41 machine. LibreOffice is not able to open files from there. When I double click one, I get this:

If I copy-paste the files on my local machine, it works fine.

I am using

Version: 24.8.4.2 (X86_64)
Build ID: 480(Build:2)
CPU threads: 16; OS: Linux 6.12; UI render: default; VCL: gtk3
Locale: en-US (en_US.UTF-8); UI: en-US
Calc: threaded

It fails not only for Calc, but also Impress (and probably Writer).

So far, all other softwares are able to open (and edit) files in this file system.

#limitations ?

like Apps/FileRoller – GNOME Wiki Archive ?

LibreOffice is using .lock-files. Can it create them “there”? (Will need write permissions not only for the file, but also for the folder.)
.
And as we live in modern times: Security settings? AppArmor or SELinux activated? LO asv"traditional" install or flatpack. If snap/flatpack: Check rights of containers to access anything outside your $home
