Here are some of my suggestions, which may not be useful, but can be used as a reference for you.
1.) Before doing any tests, I used to close the program that may affect it. For example web browsers (chrome, opera...).
2.) Turn off your Kaspersky, or all antivirus software. Then double-click StudioNEOV2.exe to see if StudioNEOV2 works. If not, proceed to the following test.
3.) Rename winhttp.dll in the same place as StudioNEOV2.exe to winhttp.dl_, then double-click StudioNEOV2.exe to see if StudioNEOV2 can work normally. If yes, the problem may be from BepInEx; if not, the problem may be that your system conflicts with StudioNEOV2.
4.) If the problem is from your system, then you have to find out whether it is a setting (system or nvidia...) or which program or library is installed that conflicts with StudioNEOV2.
5.) If the problem is from BepInEx, then you can use KKManager to help find out which plugins or mods are causing the problem.
