My point was that hide formulas must return a boolean value, not a string.

Your formula

@If(TaskName!="A"|@IsNotMember(@UserName;Author)|strFlagExpTranToZJK="1"|!@Contains(THideCon;"B");"none";"")

always evaluates to a string. It will return "none" if any of the four conditions applies, otherwise "". However, both "none" and "" are meaningless in the context of a hide formula. If, instead, you put

TaskName!="A"|@IsNotMember(@UserName;Author)|strFlagExpTranToZJK="1"|!@Contains(THideCon;"B")

then the result will be @True (which is equivalent to a numeric value of 1) in case any of the conditions applies, otherwise @False (which is equivalent to a numeric value of 0). That's something a hide formula can interpret.
