workspace cannot be moved，Nodes cannot be identified

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Two bugs:

1 After opening, the workspace cannot be moved and it freezes; it's really strange.
2 I clearly installed the nodes, but the system shows they are not installed—and the same issue persists even after I reinstalled them.

### Actual Behavior

Two bugs:

1 After opening, the workspace cannot be moved and it freezes; it's really strange.
2 I clearly installed the nodes, but the system shows they are not installed—and the same issue persists even after I reinstalled them.

_No response_

The issue does not name files, tests, or a usable reproduction path; its steps and debug log are placeholders. Start by reproducing the workspace freeze and checking whether installed nodes are recognized, then inspect the relevant frontend and node-loading entry points. Done means both behaviors are reproduced, diagnosed, and covered by appropriate verification.
