Select / deselect all results does not work

@ram4nd The issue did not reproduced , I have tried in drupal verison 11.0,7 and php version 8.3.13, used devel to generate 100 content and created a view with VBO field , but there was no error on the created view page , select and deselect all functionality is also working properly.

Doesn't seem like you missed anything.

@ram4nd, have you tried on a clean instance without any other contrib / custom modules?

It happens to me too.
If individual records are selected one by one then the export button becomes active. But if Select / deselect all results is used then the button is inactive.

I have experienced this too. As I write, I'm testing changing line 255 so that it checks element.length first. This looks so far like it makes things work for me:

if (element.length && element.get(0).checked !== value) {

I'll mark it needs work as people can replicate and we have a possible solution too.
