I am having this problem since a few versions of Studio. We have a strict policy regarding passwords and even a single bad attempt during password change process locks me out.
It seems like its not escaping all characters properly .I tried to change to ZZ123##e.123 but I also had passwords that didn't have dot in them and these ended up the same way. Changing password with the good old Assistant 12 works like a charm
Here is the error it throws :
