FoxVox launch  terminal output

FoxVox (voice commands app written in .Net7) fails to start.If run from
terminal, In messages  an "Failed to load System.Private.CoreLib.dll" error can
e seen.
From what I've spoken with author app contains all the .Net runtime libs it
needs, with exception of MS Speech to text engine. 
App launches just fine on Win7 and later.

Steps to repoduce in clean wineprefix:
 - install latest FoxVox release (2.4.0.2 used)
 - launch app using command:
     env WINEPREFIX="/home/<user>/.local/share/wineprefixes/<your_prefix>" wine
~/.local/share/wineprefixes/<your_prefix>/drive_c/Program\
Files/FoxVox/FoxVox.exe

Expeted result: App start/shows UI or at least crashes complaining about MS
Speech to text engine not found)

Actual result:
 App crashes complaining about .Net7 library failing to load.

OS: Fedora 39
Wine: 9.1 from Fedora rpms

Could it be somehow app is unable to extract bundled dependencies?
