Same with me, this issue is because of ScriptHookV they need to work on their update again. - We just need to be patient again... if your mods dont need scripthook I suggest deleting it so you can play in the meantime.
Hey, first: Have you updated your files from the new scripthook? if so... I suggest deleting dinput as it is causing issues for everyone loading up at the moment.
Hello, this issue is on-going due to not updated files so you will need to wait for the next update for ScriptHookV. In the meantime delete 'dinput8.dill' from you're GTA 5 Main Directory. If you use extra mods it may cause issues.
