If you are unable to open the Viber app on Windows 11 because it keeps crashing, this guide will provide you with the most reliable methods to fix the problem.
How to Resolve Viber Crashes and Launch Issues on Windows 11.
Method 1. Change the Compatibility Mode to Windows 7 or Windows Vista
One of the common workarounds to solve the Viber crashing issue on Windows 10/11 is to run Viber in compatibility mode for Windows 7 or Windows Vista.

1. Right-click on Viber app and choose Properties.
2. At the Compatibility tab, check the option Run this program in compatibility mode for and select Windows 7 below. Then click Apply > OK
3. Now try to open Viber again. If Viber does not open, perform the same steps but this time choose Windows Vista in Compatibility Mode.
Method 2. Set Power of Graphics Adapter to High Performance
* Note: This method usually works on laptops with a discrete graphics adapter.
Viber sometimes does not work properly on laptops where the graphics adapter's power is not set at high performance.

Another method to fix Viber not opening and crashing problems is to install a previous version of the Viber app. This approach can be effective if a recent update introduced bugs that affect the app's compatibility with your system.
* Caution: This method requires downloading an older version of Viber from a third-party website because Viber's official website does not offer older versions. Proceed at your own risk.
1. Go to Start > Settings > Apps and click Installed apps on the right.
2. Locate Viber in the list of installed apps, click on the three dots 
next to it, and click Uninstall. (Click Uninstall again to remove the program).

* Caution: During installation, avoid installing any additional program that comes with the installer.
