Some crashes I had

sign out, log back in ,restart pc, reinstall samp, reinstall gtasa. Do it in that order and it should be guaranteed to start working again.

I don't really see how logging off and on helps but everyone's first step to troubleshoot crashes like these is to delete your gta_sa.set file (resets all your control and graphics settings) which is located in your 'Documents/GTA San Andreas User Files' folder
