[GUI] Broken Input file Selection (Drag & Drop still works)

[eXhumer]

Selecting and loading any title shows this error. Were the releases checked to see if they were actually working?

Every major release gets very carefully manually tested over multiple hours covering most command line arguments and GUI settings/features. Unfortunately, I missed testing the input selection as there is absolutely no point in using it since version 4.0.0 implemented drag & drop support which is way more convenient. I definitely didn’t expect it to break because of graphical changes made to the game list layout. With an application as huge as NSZ it's quite hard to always test everything before every release and the main focus is always CLI as it's what most use. With version 4.0.0 introducing drag & drop support there also was a bias in testing that over the old functionality it replaced that worked since the GUIs existence until a few commits before the actual release. Unlike most things in this project GUI doesn't get covered by fully automated Azure DevOps CI tests what makes automated detection of such regression issues impossible.

I'm very sorry I missed testing this somewhat depreciated file selection functionally and will release a fix for it as soon as possible. 4.0.2 fixing this issue is planned to be released in the next 24 hours. Thanks a lot for reporting this bug.
