CDB process terminated unexpectedly on Qt Creator 4.12.4

Vanilla Qt Creator setup with Qt 5.15.0, happens even when compilling default Qt/Widgets app. CDB installed with latest Windows SDK.

This bug is present only on QtCreator-Windows-MSVC-161821364.7z file installed from https://github.com/qt-creator/qt-creator/releases

Qt Creator installed from online installer works.

Perhaps this file is missing some CDB-support-related files?
