How to fix Whoa Cyberpunk 2077 has flatlined error

While Cyberpunk 2077 is still in the early stages of its release, and a new patch will hopefully resolve some of the already reported issues, the community has reported some methods that have fixed the 'Whoa!' issue once and for all.

We'd first recommend doing a hard restart of your PC, as this can often resolve many issues games face when trying to launch.

The next method to try involves updating your graphics cards drivers. NVIDIA and AMD regularly release updates to ensure the best possible performance on their cards. You can download the latest NVIDIA drivers here, or the AMD drivers here.

If this doesn't work, we'd recommend trying to repair the Cyberpunk 2077 game files. You can do this on Steam by selecting Cyberpunk 2077 from your library, going to Properties and then Local Files. Here, you can click on 'Verify Integrity of game files', in which Steam will check your game files and replace any that may have corrupted.

Cyberpunk can also be launched via GOG, and repairing files on here takes a similar route. Simply right-click on Cyberpunk 2077 and select Manage Installation. Here, you can select Verify/Repair, and it should check for any corrupted files.
