Algo keeps crashing when calling get on parameter

Hi,

I have a bot that has been working perfectly fine for a long time. Since the latest ctrader update the bot seems to crash. After debugging the code and stepping through it line by line when it calls the getter for the following parameter:

 [Parameter("Enable Trading Times?", Group = "Time Management", DefaultValue = false)]
public bool TradingTimesEnabled { get; set; }

It crashes. And I have no idea why. The log file says: crashed with error #F25CBF78.

Can somebody please help me solve this?
