Could someone from the Opera organisation or moderators confirm if this problem is related to Opera browser or Windows 10?

I have this problem with Opera browser freezing on both my 4 years old Acer desktop computer and my 5 months old Asus laptop. For both computers this problem started after installing Opera 33 and Windows 10, build 10586.

When my computers was running Opera 32 and earlier with Windows 10, build 10240 this was NOT a problem.
