Incomprehensible display problem

[Alixe 9]

^{I haven't changed anything on my PC and since that day when I run P2Atc it opens but does not display the interface.here is the error indicated:}

whereas I absolutely did not launch P2Atc twice.

I restarted the PC and it didn't change anything.

Ps:    I am going to turn off my PC 15 'and restart it then launch P2Atc again, and I confirm this problem.

I closed the 10 'pc instead of restarting it and P2Atc is open without problem. But when I look at the task manager: it indicates that it is open 2 times! and that's not the case at all.
I closed and reopened P2atc it opened correctly, but the same in the task manager. it is very strange that.
