"Unable to load specified variable from file."

Is there anyone to help me about this error. I wanna use CAN messages for a project. But I couldn't replay the my records. Also I tried to a Matlab example but still I got the same error. What is the miss point in my programme?

I attached the my documents as zip. Also thee is the link of Matlab example.

load canData.mat
canFDMsgs = canFDMessageReplayBlockStruct(canFDMsgTimetable);

However there is no variable named canFDMsgTimetable in canData.mat -- the variable in canData.mat is named canData

thanks for help. I need ask you one more. I am using R2021b. I wrote the codes that in below. I got error "Can't create a std::string from this data.". How can I fix it?

load canData.mat

canMsgTimetable = blfread("example.blf");

canMsgTimetable = canMsgTimetable{1};

startTime = seconds(canMsgTimetable.Time(1))

stopTime = seconds(canMsgTimetable.Time(end))

Ts = 0.01;

startTime = round(startTime, 2);

stopTime = round(stopTime, 2);

canFDMsgs = canFDMessageReplayBlockStruct(canFDMsgTimetable);

save DriveReplayFD.mat canFDMsgs
