A fatal non-UI error - Pkhex opening error

[op.otavio]

Hello guys! 

I'm trying to edit a save but when I open pkhex, it shows me the massage "A fatal non-UI error has ocurred in PKHex." 

Below have a print with the error message and txt error report generated by pkhex.

What should I do to fix this problem?

My Net framework is 4.5

You need at least 4.6. Also make sure there's no old PKHeX.Core.dll next to your PKHeX.exe.
