Hello,
The issue appears in all products or some of them?
Also, when you update quantity check the stock to be sure that you have enough product.

I have found where is the problem:

If I enable friendly URLs it doesn't work

if I disable them this works

Do you know where the problem can be?

change the name of .htaccess to .htaccess _ and generate a new one.  Than report back

Hello Nickz

I have deactivated the friendly urls and I have cleared the cache and I have generated the .htaccess again but it does not fix my problem

Kindly share the screenshot for the "Network" tab after inspect (After enabling debug mode), as probabily you got the reason for the screen freeze or you can share the product page URL, we will help you for the same.
