Can't open the window

It works but I can’t open the window of tribler. I tried 6.5.2, 6.5.1, 6.5.0 but got same results.
I am using windows 10 32. I tried beta ver. of tribler 7 but it does not support windows 10 yet.
Acutally I had no problem with 6.5.2 for years but sunndely I got this problem last week.
Anybody can help for me?

Our upcoming release (Tribler 7 RC3) should support Windows 10 without any problems. We hope to release it somewhere the coming weeks.

Also, the current release (Tribler 7 RC2) is actually tested on Windows 10 and should work. Maybe there’s a program interfering with the window manager?
