(Probably Useless) Dump Files For ntdll!NtWaitForWorkViaWorkerFactory+0x14 and win32u!NtUserMsgWaitForMultipleObjectsEx+0x14

SUMMARY

When I add any path to Elisa "Configure Elisa" > "Add New Location", it crashes due to a QML loop.

STEPS TO REPRODUCE

1. "Menu"
2. "Configure Elisa"
3. "Add New Location"
4. In the System.Windows.Forms.FolderBrowserDialog GUI, I selected "\\wsl.localhost\fedoraremix", which caused it. Then, to ensure it wasn't WSL-specific, selected "C:\Users\rokej\OneDrive", which also did.

OBSERVED RESULT

It indefinitely hangs. In WinDbg, I see the undermentioned repeat hundreds of thousands of times:

> Qt Quick Layouts: Polish loop detected. Aborting after two iterations.

Occasionally, it's interspersed with:

> qrc:/qml/ElisaConfigurationDialog.qml:38:9: QML SettingsForm: possible QQuickItem::polish() loop
> qrc:/qml/ElisaConfigurationDialog.qml:38:9: QML SettingsForm: SettingsForm called polish() inside updatePolish() of SettingsForm
> Qt Quick Layouts: Polish loop detected. Aborting after two iterations.

I tried to capture a usable trace, but I doubt I did. Most of the time, I saw:

However, once, I saw:

The most potentially useful one thus far was:

I don't think it's related, but IDK.
