Crash site as soon as products are synchronized – [WooCommerce Square] Review

I don’t understand this extension.
Every time I activate it, thinking that maybe the bugs have been worked out, my site crashes when the products are synchronized.

Your sales teams want us to do without stripe and use Square alone, but how can I do that if your extension crashes my site every time I use it?

is there another way to synchronize my products with my checkouts?

Thanks
