### Issue Details

* **Electron Version:** 
  * v11.2.2 
* **Operating System:** 
  * macOS 11.0.1 
* **Last Known Working Electron version:**
  * <!-- (if applicable) e.g. 3.1.0 --> v10.x.y (but only on Mojave, see "Additional Information") 

### Expected Behavior
<!-- A clear and concise description of what you expected to happen. -->
When I call `navigator.bluetooth.requestDevice({ acceptAllDevices: true})` I expect a promise to be returned, as described in the [documentation](https://developer.mozilla.org/en-US/docs/Web/API/Web_Bluetooth_API).

### Actual Behavior
<!-- A clear and concise description of what actually happened. -->
When I call `navigator.bluetooth.requestDevice({ acceptAllDevices: true})` (or any other Web Bluetooth API call) electron crashes with the following error trace from the terminal:

The log can be seen here, but nothing in it stands out to me:

### To Reproduce
<!--
Your best chance of getting this bug looked at quickly is to provide an example.
-->
I've added a small example for you to try out here: https://github.com/JakobOffersen/electron-bluetooth-issue
Steps: 
- Clone the project: `git clone https://github.com/JakobOffersen/electron-bluetooth-issue.git`. There is only the `main` branch. 
- Run `npm install`
- Run `npm start`
- Click the "Use Web Bluetooth" button 

<!--
For bugs that can be encapsulated in a small experiment, you can use Electron Fiddle (https://github.com/electron/fiddle) to publish your example to a GitHub Gist and link it your bug report.
-->

<!--
If Fiddle is insufficient to produce an example, please provide an example REPOSITORY that can be cloned and run. You can fork electron-quick-start (https://github.com/electron/electron-quick-start) and include a link to the branch with your changes.
-->

<!--
If you provide a URL, please list the commands required to clone/setup/run your repo e.g.
```sh

### Screenshots
<!-- If applicable, add screenshots to help explain your problem. -->

### Additional Information
<!-- Add any other context about the problem here. -->
I've run the sample project on 2 macOS versions and I found the following: 
- On MacOS Big Sur (11.0.1): Electron `beta`, `v11`, `v10` and `v9` all lead to crashes.
- MacOS Mojave (10.14.6): Electron `v9` and `v10` works as expected, but `v11` lead to crash.
