Libreoffice takes forever to open and especially to start Slideshows (GObject-Critical)

[ACOne]

Hello everyone!
I’ve been having this Issue for multiple Months now, where Libreoffice takes up to 2 minutes to open, and over a minute to launch a simple slideshow.
Any Ideas o how to fix this? I tried to use libreoffice-fresh aswell as libreoffice-still, I tried to uninstall it, and many other things. Do I need some special support package for XFCE maybe? I can’t really figure it out.
I am running the latest build of Manjaro Linux (XFCE). Version Info from Libreoffice is attached below.

In the Terminal, it usually throws the following Errors when launching (It does launch, but it takes FOREVER, on very modern hardware)

(soffice:4402): GLib-GObject-CRITICAL **: 13:49:44.251: invalid (NULL) pointer instance

Thanks in advance for your help!

That exact issue also appears when:
Trying to change Textcolors in Impress
Trying to change format in Impress
Trying to add the first new slide to a presentation
Creating a new Presentation

It’s always:

Once it loads, you are able to change the Impress Format a few Times, until it takes multiple Minutes to open the Drop down again.

ANY Ideas on how to fix this?

Managed to find a Workaround:

LO 7.5.3.2 very slow to start

… which is why the full info from the LibreOffice is doubly important (thanks for providing that!). Are you confused by the “random” word? Not everyone has to know what distros may exist, and what flavors they have, and what their local policies are, to be able to answer questions related to LibreOffice here; for everyone outside of the bubble, they are random See also: Slow startup time It seems, the Linux-specific bug can be still not filed (?) Or: tdf#155564 tdf#155498 tdf#15522…

(Another Link, in this Case to GNOME, which lead me to the manjaro Forums)

Very slow startup on some apps after update

There is a [bug ](The aforementioned link that I can’t post due to the link limit for new users) with xdg-desktop-portal-gnome (more details [here (again, link limit)]

Workaround for gtk-based desktops (including Xfce)

sudo pacman -Rdd xdg-desktop-portal-gnome
sudo pacman -S xdg-desktop-portal-gtk

The Post also discusses Workarounds for other UIs/Desktopmanagers, so check it out if you also face this issue!

So basically, uninstall xdg-desktop-portal-gnome and make sure to install the gtk version, as the GNOME one forces a 2-3 minute Timeout.
