I just got this error too in Craft CMS 4.3.2.1

foreach() argument must be of type array|object, null given in ../vendor/lewisjenkins/craft-dynamic-fields/src/fields/Checkboxes.php line 53

Did you ever resolve it?

My error seems to have gone away again. Not sure what caused it.

Getting same error, any solutions?

My feeling is that it's related to this: #40 if ( ! $value && $this->isFresh($element) ) :

[rajparekh-pd]

I was able to fix these errors as one of my dynamic field had old twig syntax. As soon I followed craft migration guide it started working.

Thanks for the help!
