15.0 and after versions instantly crash when opened

Describe the bug

When I try to open 15.0 or after version of Optimizer, the window does not function for a few seconds and crashes.

14.9 and before versions work without any problems.

Expected behavior

@qyurila Seems the crash error is happening too early to be logged inside the app's logger. Can you inspect the Event Viewer? also check that .net framework 4.8.1 is installed

@hellzerg Here is the event log:

So it seems that Optimizer is trying to use .NET 4.0. The thing is, I don't think .NET 4.8 is not installed on my PC unless I have no idea how to install it properly.

When I try to install it with the online installer, it says '.NET Framework 4.8.1 or a later update is already installed on this computer', even after I temporarily uninstalled the .NET 8.0 SDK. I also tried to enable 4.8 through the 'Turn windows features on or off' window. Optimizer still crashes with the same exception stack even after all of this (and a restart).
