I've seen your logs, and your SSLA log isn't the same as mine when I encountered the problem. Maybe you can try installing some C++ redistributables and .NET runtimes. After that if it still does not work try to remove all of the ELS configs and see if the issue is caused by a corrupted ELS config, or just try reinstalling the game and these vehicles but I suppose you already did that. If it still does not work, maybe you'll have to reinstall your operating system. Reinstalling operating system can fix 99.9% of issues, when the system files are corrupted some GTA mods could not load properly. I was unable to open EUP Menu no matter how I tried to fix it, and in the end reinstalling operating system solved my problem.😁
