Virtual camera is not working on MacOS

I have added
```
"obs-studio-node": "https://s3-us-west-2.amazonaws.com/obsstudionodes3.streamlabs.com/osn-0.9.5-release-osx.tar.gz",
"node-window-rendering": "https://slobs-node-window-rendering.s3-us-west-2.amazonaws.com/node-window-rendering-1.0.12-osx.tar.gz"
```
in my package.json file.

App is working fine and preview is also working fine. virtual camera plugin is also installed that is visible in google meet. In the app when I click Start virtual camera then it does not start virtual camera. `obs64` cpu usages becomeo more than 100% and my laptop battery drains quickly.

On starting virtual camera in log I see
```
