It's possible that you don't have the proper CODECS installed.

You might try downloading and installing VLC Media Player and using it.  It's open source and supports most, if not all, codecs.

Steps to fix windows 11 screen flickering in some apps

Fix 1. Check for Loose Connections and Monitor

The first thing you should do is to check if the connections between your CPU and monitor are loose. To do so, you can disconnect the wire/cable and reconnect them to monitor properly. If the Windows 11 screen flashing still appears, it may indicate that the wire/cable may be damaged, then you need to replace the cable with a new one. In addition, you can connect the cable/wire to another monitor to ensure that it’s indeed faulty.

Fix 2. Disable the Dwm.exe Process in Task Manager

Desktop Window Manager  (dwm.exe) is responsible for enabling visual effects on your desktop. However, some users report that this process sometimes freezes and starts working incorrectly, which can cause screen flickering in Windows 11. To fix the issue, you can try disabling dwm.exe in Task Manager.

Step 1. Press Ctrl + Shift + ESC keys to open Task Manager and click on More details.

Step 2. In the Processes tab, right-click Desktop Window Manager and select End task. Then you can refer to the steps to end other conflicting processes.
