System.NullReferenceException Error when opening or closing Mediaportal configuration AND 'Invalid File Handle 32' during installation.

Operating System Win 10 pro 64 bit with all updates
Intel Core I5
My problem is that cant save changes in the settings of the media portal configuration becouse of this error:

the input string has the wrong format

System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.

(here come a lot more) stuff...

I already completly de/ reinstalled Mediaportal and also tryed the Pre-release Version and de/reinstalled Visual C++ (all of them), Msql ...
Next step would be setting up Windows but ... I don´t want to :-(
This Problem is accouring couple of month ago but i don´t mind. Now i bought a new 4kTV and wanted to try some new settings but as i said above, i can´t save the changes..
Sorry for my english, hope of some good ideas :unsure:

    hello, @Messor
    please can you provide wachtdog log ?

    about the file32 error during installation, we are aware of this, don't worry about that it's only error for installing font already present in system.

    Can you try to copy the folder to c:\MP for example ?
    Also just to confirm that MP can start, you can try to extract this folder to where you want like C:\MPTEST and see if it start :) :)

    I have also seen those crash on my laptop and not sure why but it seems related to anti-virus that broke something on install, i have excluded from Defender / MalwareBytes :p

    Hi sorry for having to wait ...
    I tested the zipped files and mediaportal starts without errors. (ok i cant start to look TV of course) but the configuration.exe throws out the same mistake as before. (screenshoots ) first picture is at the starting of the program and 2nd is when i try to close it.
