Nope...this freezing problem has been happenning for many days with latest fix 299, for many people....all you can do is try a factory default/reset 3x (make sure you write down and save all settings first), load a factory bin, set default key, reload fix 299, and then do a reboot...
Reducing the number of scanned channels to less than 400 does help. I had to do this several months ago and again two days ago to check and it does work.
