LO is installed from the snap.
Deleted user profile. No success.
Copied fonts to /snap/libreoffice/247/usr/share/fonts. No success.

Problem:
Open LO Writer.
On format toolbar, click the font menu box to list fonts.
Very long delay to show list of fonts: about 15 seconds.
Cannot scroll up or down to find a font.

I'm facing the same problem.
Deactivating "Show preview of fonts" in LibreOffice view options make things faster... but font preview is lost obviously.

fontconfig version 2.14 released on 2022-03-31 includes a huge performance boost related to this problem. The relevant code change is https://gitlab.freedesktop.org/fontconfig/fontconfig/-/commit/8022ab4aff469a8f095ce3168d879d3e0b3605ef

I have Arch Linux and they shipped the 2.14 version and font selection list for me is quite fast with gtk3 LibreOffice.
