Application.OpenURL(url) causes crash on UWP

Unity Engine

UWP build crashes when calling OpenURL, though the web page is loaded in the browser successfully. I can’t see any debugging info showing why this happens. Not specific to the URL: https://www.google.com triggers it as well.

Do you have a stacktrace for the crash? Can you report a bug?

I’m not the OP, but I have the same problem. Pretty simple, just an “Application.OpenURL(url)” call and it will open the browser, but it does then crash the game completely without a stack trace being sent through to the Unity logger (nothing in the UnityPlayer.log). I ran it through Visual Studio, and I am getting this as output when it crashes on my Windows 10 Pro development machine with OS build 19041.804. Project was built with Unity 2021.1.4f1

FWIW, since I already was using the WSANative package, I switched to using “WSANativeLauncher.LaunchUri(url);” for UWP, and that works great with no problems at all. Clearly there is a bug in Unity causing this crash, which seems to be around trying to release an invalid reference.

Does this repro with any URL? Say Application.OpenURL(“https://google.com”)?

Yes, last time I was testing it. Could submit as a bug but tbh not had the time. Just make a simple app with a button calling OpenURL. Crashes every time, no matter what the URL.

7

I’m running into this as well. Any info when it will be resolved?

8

I don’t think we ever received a bug report. Can you report one?

9

I tried to make a test project, but it doesn’t seem to crash there.

10

I am also experiencing this error when testing on a TOUGHPAD. The app will take me to the link, but then crashes when I try to return to the application. I’m on Unity v2020.3.15f1.

11

(Case 1382236) - Application.OpenURL(url) causes crash on UWP opened up as we are also getting this

12

Thanks we’ll take a look!

13

What could be another possible workaround with this?? System.Diagnostics.Process.Start() doesnt seem to work either…

14

You could use Windows.System.Launcher.LaunchUriAsync. Application.OpenURL on UWP is just a wrapper around it.

Okok. I’m trying with this:

#if (ENABLE_WINMD_SUPPORT || UNITY_WSA || UNITY_WSA_10_0)
using System;
using System.Threading.Tasks;
using UnityEngine;

namespace Util
{
    public static class UWPStartUriProcess
    {      
        public static async Task Start(string URL)
        {
            try
            {
                var options = new Windows.System.LauncherOptions();
                options.TreatAsUntrusted = true;
                var success = await Windows.System.Launcher.LaunchUriAsync(URL, options);

                if (success)
                {
                    Debug.LogError("Opened - " + URL);
                }
                else
                {
                    Debug.LogError("Failed to open - " + URL);
                }
            }
            catch (Exception e)
            {
                UnityEngine.Debug.LogError("Failed to open URL: " + e);
            }                     
        }    
    }
}
#endif

I get the following error when building UWP: Assets\Scripts\Utils\UWPStartUriProcess.cs(14,72): error CS1503: Argument 1: cannot convert from ‘string’ to ‘System.Uri’

Do you know what could be going on? :hushed:

16

Can I ask from where did you get that WSANative package?

17

You need to construct the URI using “new Uri(URL)” and pass that to the Windows API.

@AlfEspinosaN I think he’s referring to this asset
