Description:
When launching MySQL Workbench on Windows, the application crashes with the error:

"Desktop composition is disabled. The operation could not be completed because desktop composition is disabled. (Exception from HRESULT: 0x80263001)"

This happens immediately after opening the application. The issue prevents normal usage.

How to repeat:
1. Open MySQL Workbench
2. Wait for application to load
3. Error message appears and application crashes

Suggested fix:
Possibly related to Windows display settings or graphics driver. Enabling desktop composition or updating GPU drivers might help.

This issue applies to the legacy MySQL Workbench 8.x implementation that is no longer supported or maintained.
MySQL Workbench 26.7 is a complete rewrite using a new technology stack and does not use the affected legacy implementation.
Therefore, this issue is not applicable to the current MySQL Workbench product and as such is closed.
