Issue with lme4 and Matrix in RStudio

Hi,

I am trying to create some geostatistical plots on RStudio, for which I need the packages lme4 and Matrix. My current versions are R 4.3.2 and RStudio 2023.12.0 and I cannot update them as I don't have the privileges on my system (although I've asked the helpdesk to update both).

I keep running into this error:

Error in initializePtr() : 
  function 'cholmod_factor_ldetA' not provided by package 'Matrix'

I've tried to follow solutions like this one ad reinstall lme4 from sources but nothing changes. As pointed out here.

I'm pretty desperate since the rest of my code is fine, but this roadblock is keeping me from doing pretty much anything. Any help will be much appreciated!
