@Deathmatic The Road disappearing, i had this with another mod. But i couldn't configure out which one. Do you had any map mods installed? Business packs, Casino updates, extra buildings or areas?

Ok, i see revive is a map mod which bring new probs too.
Found this tutorial. It's for the policemod but there are some tweaks in the graphic options you can do, for the missing textures.

@neogeo39 And are you sure that it is the number of vehicle mods?

@21davy21 For me it looks like that it has something to do with the redux mod. But thats only a guess.
The next i would try is to use another gameconfig (not the one from the mod). And because its a graphic mod maybe it helps to update your graphic driver.

Found this guide to redux maybe it helps you, but don't forget to backup everything you change.

Okay the wonky format is working too, just tested it with another mod. Had some cases where it was the solution with another slash format. Just ignore my post before, then. I copied the wrong format again.

The format from chonkie should fix your mods.

Can you start the game without mods?
Otherwise have a look to your windows logfile for the crash.

@chonkie

Nope, i only see 2 empty posts and an undefined link in the quoted text.

@Nightbeast765

Like chonkie said: You need to correct the slashes or the program can't find the lines. In some mods or tutorials are the slashes to the wrong side.

wrong:
<Item>dlcpacks:\18ram</Item>
<Item>dlcpacks:\00f350dually</Item>
<Item>dlcpacks:\bigtex</Item>
<Item>dlcpacks:\17jamb</Item>

right:
<Item>dlcpacks:/18ram</Item>
<Item>dlcpacks:/00f350dually</Item>
<Item>dlcpacks:/bigtex</Item>

Clicked on "Menyoo customs" and spawned all vehicles in the menu "emergency". All worked. Not sure which version im actually using. I think im using an old (1.0.0) one. The very first from 21. February 2019 https://files.gta5-mods.com/uploads/menyoo-pc-sp/9ed97c-MenyooRelease.rar

@ ArmaniAdnr
Maybe you had activated the autorepair option.
