Bugs are not the reason the game failed.   Games like Skyrim prove that people will look past bugs to enjoy an ambitious high concept game.   Cyberpunk failed because the core promise were not delivered; the game was barely an RPG by the time it launched.   It was much more like a GTA knockoff.   Someone at CDPR made the bad call to take inspiration from GTA while having 1/5th or less of Rockstar's budget.
