What platform are you experiencing this issue on?

Windows x64

What version of UWB are you using?

2.2.5

What Unity version are you running?

2021.3.26f1

Describe what the issue you are experiencing is.

Unable to use UWB on Mac. I'm getting "Error in data loop! System.IO.EndOfStreamException: Attempted to read past the end of the stream." on my Mac M3 Max.

Provide reproducible steps for this issue.

1. Add Web Browser Full to my scene
2. Set "Popup action" to "Open External Window".
3. Set initial URL to https://javascript.info/popup-windows
4. UWB successfully loads the page
5. Under the "Example: a minimalistic window" section, there's play button in the example code. Click on the play button which then launches a pop-up.
6. Close the pop-up

[UWB]: Error in data loop! System.IO.EndOfStreamException: Attempted to read past the end of the stream.

[UWB]: An error occured while executing task SendMouseMoveEvent! System.IO.EndOfStreamException: Attempted to read past the end of the stream.

[UWB]: It appears that the engine process has quit!

Any additional info you like to provide?

I am having the exact same issue. Following are the details:

• System Info: Mac M2 Pro with Mac OS version 15.2
• Unity Version: 2021.3.45f1 (Intel)
• UWB Version: 2.2.5

Please provide a solution for this. I'm currently stuck.
Thanks in advance.

I've taken a look at this issue and have replicated it in a MacOS vm. The engine process is crashing, the crash seems to come from CEF, and is probably something to do with UWB's plist config, but not too sure. Need someone with better MacOS know-how to look.
