Hello @Deathrezen

We verified this issue on the lates 2.4-develop branch code.
There are no exceptions now in logs and the page opened successfully.
But I gree validation make sense anyway!

We checked by adding the "Catalog Products List" widget on the Home page.
Current behavior:

• Number of Products to Display = 5a -> Result: 5 products are shown on Home Page
• Number of Products to Display = zas4 -> Result: 1 product
• Number of Products to Display = azazaz -> Result: 1 product
