Blank White Screen on Startup + Sync Not Working in Background (Windows)

Bugs and issues
1

Version: Insync 3.8.11.50514
OS: Windows 11

Description

When launching Insync, the application window opens but remains completely blank (white screen). The UI never loads, making it impossible to interact with the application.

Additionally, background synchronization is not working. Files are not being synced, and Insync appears to be non-functional even after restarting the application.

I found several reports in the Insync forums describing similar blank UI issues on Windows, including reports affecting Windows 11 users.

Steps to Reproduce

  1. Launch Insync.

  2. Wait for the application to initialize.

  3. The main window remains blank/white indefinitely.

  4. No synchronization occurs in the background.

Expected Behavior

  • The Insync UI should load normally.

  • Background synchronization should start and function correctly.

Actual Behavior

  • The application window stays completely blank.

  • No background synchronization occurs.

Troubleshooting Already Attempted

  • Deleted %APPDATA%\Insync and %LOCALAPPDATA%\Insync, then restarted Insync.

  • Performed a complete uninstall and reinstalled the latest version.

  • Updated GPU/video drivers to the latest available version.

  • Rebooted the machine after reinstalling.

Additional Information

  • Issue persists after a clean reinstall.

  • Issue persists after removing all Insync user data.

  • No change after updating graphics drivers.

Hi @Hugo_B, apologies for the huge trouble! Could you please let me know if you have a VPN, antivirus, or proxy setting that could be blocking Insync?

Kindly send your logs.db and out.txt files to support@insynchq.com with the link to this post. I’ll be escalating this to our Windows Team for further assistance.
