I wasn't having this issue up until a couple weeks ago now none of my previews with Xcode 12.3 are working. I just get the following error when they attempt to render
RemoteHumanReadableError: Failed to update preview.
The preview process appears to have crashed.
Error encountered when sending 'previewInstances' message to agent.
==================================
| RemoteHumanReadableError: The operation couldn’t be completed. (BSServiceConnectionErrorDomain error 3.)

| BSServiceConnectionErrorDomain (3):
| ==BSErrorCodeDescription: OperationFailed
It's beyond frustrating.
