ERROR: ldconfig failed, exit status 256

Hi there. I just installed the latest version of LibreWolf using your flatpak package. Tried to open LibreWolf, but it gave me this error: ldconfig failed, exit status 256 Not sure what this means or what I can do to fix it. I'm running Ubuntu 20.10 btw and Linux kernel 5.10.0-5.1-liquorix-amd64. Thanks in advance!
