I haven't tried it yet because I don't have another PC here to test it :))... You or a friend of yours should edit this file: "\Schedule I_Data\Plugins\x86_64\steam_settings\configs.user.ini", change "account_steamid=....." to another number and save it.
If you're having the same issue as most people with "Needin' the Green" quest, go to your file explorer and search, %appdata%, locallow, tvgs, savegame, your save, money.json, change your lifetime earnings value to a positive value and this should fix your issue.
(I made my value 7650, went to main menu and relaunched save. now quests 7650/10,000)
