Advanced Select `removeOption` doesn't work after update

Summary

Advanced Select add & remove options don't work after update

Steps to Reproduce

Tried using the example component in the docs

1. Click "Add Three Options" button
2. Click "Remove values 5,6,7" button
3. View console for error

Demo Link

https://preline.co/docs/advanced-select.html#add-remove-options

Expected Behavior

• The removeOption should work as intended.
• No console.log messages should be shown, especially in production.

Actual Behavior

• console.log messages are shown, seems to be and the affected option's val values and false
• The console throws an error: Uncaught TypeError: Cannot read properties of null (reading 'length') and doesn't do anything else.

Seems to occur in single select dropdowns, the multiple select example in the docs has no issue.

This also happens in one of my projects, when I tried upgrading the package version due to this bug: #414 , where in my case no items are removed.

Preline version: ^2.4.1
Chrome version: Version 126.0.6478.185 (Official Build) (arm64)

@umaraziz0 Hi,
Thank you for bringing this to our attention, we're appreciate it!
As far as I can see this error doesn't affect functionality and you can continue to use this functionality despite the error in the console.
We will fix this in the next update.
Best regards!

Find a solution to this problem by using try catch construct. So in catch we can handle errors and in finally continue executing the code!

        const endMinutesSelect = HSSelect.getInstance('#minutesEnd');

           try {
                endMinutesSelect.removeOption(optionsToDelete)
            } catch (error) {
               
            } finally {
                endMinutesSelect.addOption(newOptions);
            }

How to remove all the select options?

Need to remove select options without knowing the keys as options are remotely fetched.
