"Delete browsing data" in Settings (Web Console) crashes NETworkManager

[erptechnician]

Describe your issue:

Deleting browsing data (WebView2) in the Web Console section of Settings causes NETworkManager to crash to the desktop. This issue is reproducible on my installation.

Steps to reproduce the issue:

1. Open NETworkManager with admin privileges.
2. Enter password for profile encryption.
3. Navigate to Settings > Web Console.
4. Click "Delete browsing data" button.
5. Click "Delete" button in popup dialog to confirm.
6. NETworkManager crashes without displaying an error and user is returned to the desktop.

NETworkManager version:

NETworkManager 2025.8.10.0 (regular install - not portable)

Windows version (like 10.0.x.x):

Windows 11 Professional version 24H2 (OS Build 26100.6584)

.NET version (like 6.0.x):

Microsoft Windows Desktop Runtime 8.0.20 x64
Microsoft .NET Runtime 8.0.20 x64

Should be fixed in the next release. I will make a pre-release in the next few days, so you can test if it works.
