Weird Crashes when Trying to show Custom Model

Well, whenever I try to load a certain model that I made via the search menu, it never loads the spawnicon, and it automatically crashes once it’s appeared on the spawn menu. Ive also had MAJOR trouble loading spawnicons for regular things, and its honestly getting a bit annoying having to restart Steam every time, seeing as how I get an error every time I try and start the mod a second time anyway. Any help?

This may be an issue with the new Gmod updates

I wish Garry would just go ahead and revert to an older version and admit the updates failed.
