For WhatsApp Desktop on Windows 11, a known recent cause of the app and its content (chats, images, files) not working properly is a problematic Windows Insider/preview update.
From similar app issues, one effective fix is to uninstall the specific Windows update that broke the app and then pause updates until a newer build is released.
Follow these steps:
- Open Settings > Windows Update.
- Select Update history.
- Scroll down and select Uninstall updates.
- In the list, locate the problematic update (for similar WhatsApp issues this was KB5079491 on an Insider build).
- Select it and choose Uninstall.
- Restart the PC when prompted.
- After restart, go back to Settings > Windows Update and use Pause updates for a few days until a newer build is available that fixes the issue.
If the problem started exactly after a recent update and uninstalling that update restores WhatsApp Desktop functionality, keep updates paused temporarily and then resume later to pick up a fixed build.
