The database flows could not be loaded

Bug Description

The software appears black and I cannot create or edit the agent.

Reproduction

1. Download the Desktop installer from the website.

2. Create an Agent flow for automation.

3. Then update the software using the "New version available" notification.

4. When I reopen the program, I can't see the flow I created.

5. The screen is black and the error message "The flows could not be loaded from the database" appears.

Expected behavior

When opening an automated agent, you would need to see the agent's node workflow.
