Installed many mods on cars as well as Benny's Original Motor Works in SP (SPB_1.9), Fleeca Bank Heists, NSFgauge-2.63.2, SimeonRepoV1.2.1, The Diamond Casino Heist BETA, The Pacific Standard Heist, AfterHoursSP1.2.1, Vangelico and after that, quests began to hang for me, that is, I cannot go through the game further, how can I fix this?
Also, when I try to load previous saves, I almost always get a crash

@ReNNie I did save 2 minutes ago and loaded it and got crash

When I go into the game and try to start the previous save, I crash to the desktop, I tried to change gameconfig but absolutely all of them crash when loading the previous save

@Lil-Slim-C It’s painting the car so that it has all sorts of patterns or characters from films, let's say Darth Maul

Friends I want to paint a car, with what program can I do it?
