Hi This is quite less information for us to tell why adding TWI caused error. You need to give more information like which SDK and softdevice version you tried and which sensor you were trying to connect to using TWI? and where the error fatal was returned. Was it the driver code or your application code? can't you set a breakpoint and see the call stack and see what might have caused this error?
