How to reproduce:
1. Install and configure the Unity Accelerator
2. Create a new project
3. In the Editor, go to "Edit -> Preferences -> Asset Pipeline", change "Default Mode" to "Enabled" and set "Default IP address" to your configured Accelerator address
4. Press "Check Connection" and confirm that connection is successful
5. Import any assets into your project (e.g. from the Asset Store) for them to get uploaded to the Accelerator
6. While the assets are importing, interrupt the Accelerator connection (e.g by disabling the Unity Accelerator service)
7. Observe the asset import
Actual result: The asset import hangs infinitely until the Editor is restarted forcibly
Expected result: The asset import does not hang and continues once the connection is restored
