Exception handling of running functions in a dialog

[win]

Hello,
Running the function(func3) from the dialog, I have encountered the following problems

about func3:
line 1.
Will pop up an error message，I don't want to pop up an error warning, I need to continue

line 2.
Dialog will lose response, QM quit unexpectedly, dialog crashes

 My Request:
1.When the above three lines of code have an error, run the 5th line code directly.

2.Executing some function through the button in the dialog box, any abnormality in the function will cause the dialog box to close unexpectedly, how to prevent it?

is it possible? Any suggestions are welcome, thanks in advance
