I confirm:

Symptoms

Splash screen appears, some text displaying content its loading appears and then it just silently closes/crashes. Appears to use .NET

I have little hope of this ever actually running as the SDK is essentially a striped down version of UDK 3 (I think), but here's a thread for it regardless. Would love to be able to make some KF2 maps on Linux.

Reproduction

Install the SDK via the tools library in steam and run it.

steam-232150.log

Review the linked steam-232150.log alongside the reported Proton 4.2-3 and system information; reproduce the issue by installing the SDK from Steam's tools library and running it. Done means determining whether the silent crash can be reproduced and documenting a confirmed compatibility result or actionable cause.
