Hey @Nuan-Yang - I'm not sure there's enough information here to go off of. Do you have code you can share, stack/dump, or a sample app which reproduces this problem? Thanks!

[Nuan-Yang]

hey @champnic I uploaded the sample project https://github.com/Nuan-Yang/cag-studio , you can build and run this demo, and Drag the black bar at the top https://github.com/Nuan-Yang/cag-studio/blob/main/images/image1.png, This problem occurs when you hold down the mouse and drag the form for too long

I have the same problem too.

[champnic]

Sorry for the delay, I've added this bug to our backlog. From initial guess I would say that the SendMessage is blocking some other message from being handled.

[TotoroJason]

Your guess is correct. I had the same problem, but when I replaced SendMessage with PostMessage, it didn't happen again.

@champnic hey

在使用 FolderBrowserDialog 打开文件夹的时候, 我在主线程(UI线程) .ShowDialog() 长时间无操作会导致 软件闪退并报错 ; 然而,使用 OpenFileDialog() 却并未发生任何事情 我很疑惑,该如何处理这个问题

When using FolderBrowserDialog to open a folder, I am in the main thread (UI thread) .ShowDialog() if there is no operation for a long time, the software will crash and report an error; However, using OpenFileDialog() nothing happens I'm wondering how to deal with this problem

C# CODE MainWindows.form.Invoke((EventHandler)delegate { var fileSave = new FolderBrowserDialog(); if (fileSave.ShowDialog() == DialogResult.OK) { .... } }

@Liuwenjie0720 Can you share a sample app that reproduces this error? Or can you share the stack when this error occurs? Thanks!

Hello @champnic, I hope you are doing well; is there an update on this defect? Our logs indicate the exact issue.

We have a client who is getting this issue; I am attaching an eventvwr file with the error. For this crash, we are running in a Excel Addin, x64bit. This is a stable software version; with thousands of clients; it is running:

• WebView2 Fixed runtime version: 88.0.705.81
• WebView2 SDK: id="Microsoft.Web.WebView2" version="1.0.705.50" targetFramework="net48"
• Winforms

This client has suggested two possible causes:

• Three recent WindowsHot fixes
• Contention with another Plugin

@LK-Global I'm not sure if this is related or not - the eventvwr doesn't look to have a lot of helpful info. If you look in the <user data folder>\EBWebView\Crashpad\reports is there a dump file in there from the same time?

Given it's a fixed version, I'd be surprised about contention with another plugin, or whether a windows update would cause this. Can you share a stack trace, repro steps, or a sample app which reproduces this issue? Is it a single client running into it? Is it consistent failure, or gets fixed when restarting the add-in or excel or the machine?

[LK-Global]

@champnic Working with Microsoft Support, we used DebugDiag to produce logging. What is interesting is that the DebugDiag logs only shows the evergreen runtime loaded; our application uses a fixed runtime.

As this problem only occurs in Excel when a specific second add-in is loaded, and happens every time, I have this question: What is the expected behavior if, within a single Excel process, the evergreen runtime and a specific fixed runtime are loaded? Let me know if you want to see specific logging outputs or DMP files. Thanks for your response.

[champnic]

You should be fine to load separate WebView2 controls using different runtimes, such as loading 1 with Evergreen, and 1 with Fixed Version, etc. Is your plugin using a user data folder that might be conflicting with the other plugin? If so, can you try specifying a different and unique user data folder?

The other thing to check would be how you are specifying the Fixed Version location. It's possible that if you are using an environment variable, for example, it could be getting overridden by something else setting the environment variable before your WebView2 is initialized.

@Liuwenjie0720 我也遇到了这个问题，请问你找到解决办法了吗？
