Having the exact same issue and many guildies seem to be as well. Really annoying especially in PvP where if I want to switch characters before a match starts I have to ctrl alt del multiple times to escape the frozen loading screens and hope that I can make it back before the match starts.
Find it hard to understand how such a huge problem has persisted for the last two patches—gw2 usually runs beautifully for me so this is kind of jarring honestly. Really frustrating that we’ve had no official response either.
I’ll try the windows 7 compatibility mode thing but c’mon anet..windows 10 has been out for long enough that you should have a handle on this.
