Invoice creation error (VM4) - orders with specific shipping method only

[Can.Y]

Does anyone happen to know why I cannot create a new invoice? I have checked everywhere I can but don't have a single clue.
Joomla 4.3.4  VM 4.2.0 10905
(Fresh install J4 site)

Following is the error msg:

array_push(): Argument #1 ($array) must be of type array, null given

I modified the tcpdf.php and invoice.php files followed the revisions record.
https://dev.virtuemart.net/projects/virtuemart/repository/virtuemart/revisions/10932
https://dev.virtuemart.net/projects/virtuemart/repository/virtuemart/revisions/10921

Now, the error msg turned to
count(): Argument #1 ($value) must be of type Countable|array, null given

I found that if I stop using the shipping method "Advanced Shipping by Rules for VirtueMart", the invoice creation issue will just gone!

But I really really need to use this shipping method.
Does anyone know how to solve this?

Finally! I find it!
I removed the table element from "Shipment Description" and the invoice can be created perfectly.
(There are no such problems while in Joomla3 VM3)

Hope this helps.
