Screenshot of the error included in the attachment

Hi. I've started to get this error message about a week ago,
Every time I open OnScreenKeyboard (Win+Ctrl+O), my PC lags for 3 seconds and the error pops up,
after I hit OK on the error, I can use the OSK normally.

I have no idea what DF has to do with OSK, and I can't delete the related DLL.

[EDIT]: I did try to reinstall DF. Windows is up to date. Didn't install any new software when it started happening.

Did anything come of this? I have the exact same issue this evening when it was fine this morning (with nothing installed in between)
