Could you try this pre-release build 734, and see if you still get the same error?
https://nn.pgmusic.com/pgfiles/support/patches/bb2020_win_update_build734.exe

Tip: prior to installing, you could make a copy of bbw64.exe and name it bbw64_722.exe.
This should allow you to run build 722 afterwards (if you need to) without reinstalling the build 722 patch.
