The drop-down menu for child products doesn't work.

[Pointel]

Hi,

I installed VirtueMart 4.2.2 10908 on Joomla 4 and noticed a problem.
I created a parent product with two child products.
When I click on any child product from the drop-down menu from the FE, the text changes but not the product page.
I tried changing the template to the default Joomla one but the situation doesn't change.
The only thing different I see is the spinning wheel but no product changes.

Has anyone encountered the same problem?
How can I fix it?

Are u using ajax for your product change? If so check for JS errors in the console
