Is anyone else experiencing a crash-to-desktop when entering Hytbold using the 64 bit client?

This happens every time (tried 3 different alts, Hytbold at different stages of rebuild) for me on both my desktop and laptop PCs (both Win 10, with decent modern gaming h/w specs).

It then becomes impossible for me to log in to that character, unless I revert to the 32-bit client, and once in game, move the character away from Hytbold.
