Game crashes on startup after installing texture mod

Installed a 4K car texture pack and now my game won't even load into the main menu.

Installation: GTA 6 latest build, single .ytd replacement, tested with and without script hook.

What I've tried: verified game file integrity (nope), deleted the .ytd file (works fine without it), read the comments on the mod page.

EDIT: Fixed - ran out of stream memory. Installed a memory extender and the mod loads fine. Leaving this here for anyone else.
