Same here, i can confirm, it work when you remove search form.

So as figured out the Problem is in the plugin itself, after digging into it, paypal said the Paypal api url is NOT https://api.paypal.com. Instead i should try this URL https://api-m.paypal.com .
After changing the url in plugin, it worked fine.

Additional informations i found out.
I simply was able to disconnect the account, and the page was loading well. After reconnect or trying to reconnect the account it was not working anymore. Somehow it cant connect to paypal and then it is it hast the above mentioned problem. even through the wizard

No conlcits.
It was a Problem with an update of woocommerce, where woocommerce resettet the store country.
After i set the country correctly everything worked fine.

Same here.
