How to Fix Clair Obscur Expedition 33 Fatal Error

Like many other players, if you are also getting a constant “Fatal error” while playing Clair Obscur Expedition 33, then worry not and try all the below-mentioned workarounds one by one.

1. Fresh Install of Windows 11

First of all, try installing Windows 11 which will help to resolve crashing and performance-related issues. Here is how you can do it in a proper way:

1. First of all, back up your personal files to an external drive or cloud storage
2. Download the Windows 11 Installation Media Tool from the official Microsoft site.
3. Create a bootable USB and boot from it.
4. Select “Custom Install” and format your system drive for a clean installation.
5. Once the installation process is complete, reinstall GPU drivers, chipset drivers, and Windows updates.
6. At last, reinstall the game via Steam and you should be able to play the game without the Fatal error.

2. Update Motherboard BIOS

In case your BIOS has been outdated, it can cause several compatibility issues, especially with UE5 games and high-end CPUs. Here is how you can update it.

1. First of all, make sure the model of motherboard your system has
2. Then, go to your motherboard manufacturer’s support page
3. Download the latest BIOS update file and read the instructions carefully
4. Flash the BIOS via the BIOS interface
5. Reboot the system and test the game

3. Downgrade or Roll Back GPU Drivers

Sometimes, the latest GPU drivers bring several bugs into the game that eventually crash the game with the Fatal Error. So, the next solution suggested by several players is to downgrade or roll back GPU drivers. Follow the below steps:

1. Use DDU (Display Driver Uninstaller) in Safe Mode and uninstall current drivers.
2. Then, download a previous stable driver version:
3. NVIDIA users: Try 552.42
4. AMD users: Try 24.2.1 instead of 25.3.1
5. Install the older driver and reboot
6. Once done, try running the game.

4. Run as Administrator & Disable Fullscreen Optimization

Fullscreen optimization while playing online games including Clair Obscur Expedition 33, sometimes causes conflicts with UE-based games. If that is the case, try running the game as admin as it ensures the game has all the necessary privileges to run it smoothly on your device. Here are the steps to do this:

1. Go to the folder where the game is installed on your PC.
2. Then, right-click on the game >> Properties >> Compatibility tab
3. Check the below 2 points
4. Running this program as administrator should be checked.
5. Disable fullscreen optimizations should be checked.
6. After checking both of them, click on Apply and Ok.
7. Relaunch the game and check if the issue is resolved.

6. Submit Crash Logs to Developers via Feedback Form

If nothing works and you are still receiving the same error, then the last option is to submit crash logs and submit them in the feedback form. This will help the developers to fix the issue.
