code-server -r filename results 'error Unexpected status code: 500'

### Is there an existing issue for this?

- [X] I have searched the existing issues

### OS/Web Information

- Web Browser: Chrome
- Local OS: Debian testing
- Remote OS: Debian testing
- Remote Architecture: amd64
- `code-server --version`: 4.92.2 de65bfc9477f61bc22d0b1a23085d1f18bb25202 with Code 1.92.2

### Steps to Reproduce

1. Open code-server
2. Open an existing workspace
3. Open a file from CLI (code-server -r ...)

### Expected

code-server opens the specified file in one of the open windows.

### Actual

Some cases it works, mostly with fresh sessions, then after a while it breaks and I get only a `error Unexpected status code: 500`. I just realised that restarting the code-server instance and reloading the client window fixes the problem.

### Logs

```shell
As an intermittent issue I need to work a bit on the logs, I set verbose now.
