[bug] the webview crashes on release target

[Kiyozz]

Describe the bug

I'm building an application that will be used by Skyrim Modders. The application is launched through an app called Mod Organizer 2 (this app uses something called vfs for virtual filesystem).

I built the app first with electron 3 years ago. Today, I want to migrate to tauri to reduce the bundle size and memory usage.

When starting the app exe from Windows Explorer, the Webview starts and the application is working.

When starting the app with Mod Organizer 2, the Webview starts and you can see the app menu, a blank window app and finally the app crashes with the below stack trace.

You could say

"ok, this is a problem with Mod Organizer"

but why when I built the app with electron, I did not have this problem.

I need help debugging this.uses

Reproduction

To reproduce, make sure to have all Tauri requisites.

Node 18, pnpm 8.

You will need an MO2 environment and Skyrim LE/SE/AE game.

Inside MO2, you need to have an executable, for example ↓

repository: https://github.com/Kiyozz/papyrus-compiler-app-tauri and branch main.

1. pnpm i
2. pnpm tauri:build
3. start MO2
4. start the release target PCA.exe with MO2

Expected behavior

The webview starts successfully.

### Additional context

You may say that this is hard to reproduce because of the setup, but maybe someone comes across and help debug this!

Thanks you everyone that help into this!

Without looking too much into it (= without testing it myself) there are a few upstream issues with the same error code: https://github.com/MicrosoftEdge/WebView2Feedback/issues?q=0x8000FFFF+is%3Aissue - most seem to be permissions related, are you running mo as admin? The other issues don't seem related but hard to say rn 🤔

p.s. thx for the report :)

[Kiyozz]

MO2 is not started as admin, as everyone should 😝

I know, this is hard to test 🥲

[Kiyozz]

I just created an issue in the MO2 repository
