Problems with graphics cards?

[Colorman3605]

I went to reopen a DOS game on launchbox (I hadn't played it for a few months) and I noticed that no games started anymore. At each start I get the message "loadlibrary failed with error 126 the specified module could not be found". I went online to see if I could find anything and I think the problem is in the graphic patterns. I have a Radeon RX560 Series and an Intel UHD Graphics 630. I have tried various suggestions on the net but nothing, The only thing is to go into the settings of each single game (Dosbox.conf) and not use any hardware acceleration in the output method in the video options.
It is not a launchbox problem but since I have not found valid solutions around, I ask if someone can give me a solution. I also have a similar problem with RetroArch but here the error is "load library failed with error 87 parameter is incorrect". The solution here is to change the video driver (it doesn't have to be gl, glcore or gl1), but the playability of the games drops significantly. If I use retroarch.exe otherwise renamed then retroarch works. Here too it is not a problem but as above I ask for help.
One last thing...
It often happens to me that after changing the properties of a game (name, series or other) when I close the game edit screen the launchbox freezes and I am forced to close it manually.
Has it happened to others?
Thank you!
