If you want a stable ,trouble free DAW then as someone already;
Get rid of your 32 bit plugins.
Seriously, the bridge was just to help people transition over at the time.
On windows 10 here with Cubase 8 x64 and everything works flawlessly. I really don't think there's any plugin now that's only 32 bit that can't be replaced. And ask yourself; if a plugin hasn't been updated to x64 by now that's not a good sign. Either the Developers are no longer in business or they've abandoned it, neither scenarios are good for your DAW in the future.
