Comment (by subrataemfluence):

 Thank you for checking out on this! Yes, you are right, `explode()` might
 not be the only one. Because I faced the issue with this, I mentioned it.

 3) The comma-separated string is formed clientside when I select/unselect
 the checkboxes.

 I will work on 1 and 2 tomorrow and add as much information I can collect.

 > HI @subrataemfluence thanks for posting the problem, it's very helpful.
 Reading the ticket, I believe it's unlikely that `explode` is the problem.
 Most likely something about ` $groups             =
 $new_instance['groups'];` could be different with the block editor
 enabled. I'd like to ask you for three things, please:
 >

 widget?

 > 2) Could you `var_dump`, or inspect in xcode, ` $groups             =
 $new_instance['groups'];` with and without the block editor enabled? What
 is the value of $new_instance['groups'] in these cases?
 >
 > 3) When is the comma-separated string formed? Clientside or after save?

 > Alternatively you could attach the entire widget code so we could test
 without the back and forth.

 > Thank you!
