IN CASE ANYONE COMES ACROSS THIS, I FINALLY FOUND THE ISSUE AND A FIX TO IT. LINK TO PAST Enscape Versions.

Demian, in case someone else asks you about this, here's the temporary solution that I found. But it also raises new issues. I am using Sketchup 2021. I don't want to upgrade as I don't want to go through the painstaking process of downloading all of my plugins again. So I'll wait until late 2023 or 2024 before I decide to upgrade again. I've been keeping up to date with the Enscape updates, but somewhere down the line when I updated I lost the ability to utilize the material library. Fast forward to a couple of days ago, I updated to the latest version of Enscape 3.4 as of Jan 31st, 2023 and I lost the ability to open medium to larger files in Enscape. Once I realized it was crashing on several models during the loading phase, (something that was not happening a week ago) I uninstalled Enscape 3.4 and started working my way back to previous versions. I found Version 3.2.0 works to allow me to open these larger projects and I also discovered it allows me to fully utilize the material library. HOORAY. With that all said, I think it's a real shame I can't use the latest version of Enscape. Especially when I just renewed this product several days ago. Maybe using Sketchup 2021 is the issue? Maybe not. Either way, I think from now on I'll stay several versions back on updates.
