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.

Title:
  libreoffice font selection unusably slow

Status in LibreOffice:
  Won't Fix
Status in fontconfig package in Ubuntu:
  Incomplete
Status in libreoffice package in Ubuntu:
  Incomplete

Bug description:
  Trying to scroll through the font list in the menu bar, I experience
  an unacceptable degree of lagging. Just popping up the dropdown list
  takes 7-10 seconds and the system takes the same amount of time to
  respond to perform individidual scrolling gestures. The CPU jumps to
  100% and the whole system becomes unresponsive.

  I have tried deb, snap and even the packages offered on the site of
  the LibreOffice project. They all manifest the same behaviour. The
  only thing that works is disabling font previews. I have downgraded to
  7.2 for now, which appears to be unaffected.

  I have contacted the LibreOffice team and they tell me that this
  should be solved by fontconfig 2.14. Unfortunately, Ubuntu 22.04 is
  shipping 2.13...
