There has been a critical error on this website when I setup woocommerce paypal

Hello everyone
I got a problem when I tried to set up the woocommerce paypal checkout plugin.

Here is the thing: The first time when I downloaded and installed this plugin,there is no error, and then I went to woocommerce—setting—payment—paypal checkout to setup(fill in my paypal account infomations) the plugin, the page which I got is diffirent than any others in the tutorial videos: instead of filling in the live API username/password/signature, the page asked me to fill in the live merchant ID/ live clinet ID/ live secret code. I found these infomation in my paypal account developper section and filled in. and then, the error show up

Fatal error: Uncaught WooCommerce\PayPalCommerce\ApiClient\Exception\RuntimeException: Could not create token. in /home3/speeddll/public_html/tacticalshop/wp-content/plugins/woocommerce-paypal-payments/modules/ppcp-api-client/src/Authentication/class-paypalbearer.php:122 Stack trace: #0 /home3/speeddll/public_html/tacticalshop/wp-content/plugins/woocommerce-paypal-payments/modules/ppcp-api-client/src/Authentication/class-paypalbearer.php(97): WooCommerce\PayPalCommerce\ApiClient\Authentication\PayPalBearer->newBearer() #1 /home3/speeddll/public_html/tacticalshop/wp-content/plugins/woocommerce-paypal-payments/modules/ppcp-wc-gateway/src/Settings/class-settingslistener.php(150): WooCommerce\PayPalCommerce\ApiClient\Authentication\PayPalBearer->bearer() #2 /home3/speeddll/public_html/tacticalshop/wp-content/plugins/woocommerce-paypal-payments/modules/ppcp-wc-gateway/src/class-wcgatewaymodule.php(236): WooCommerce\PayPalCommerce\WcGateway\Settings\SettingsListener->listen_for_vaulting_enabled() #3 /home3/speeddll/public_html/ in /home3/speeddll/public_html/tacticalshop/wp-content/plugins/woocommerce-paypal-payments/modules/ppcp-api-client/src/Authentication/class-paypalbearer.php on line 122

Then, I tried to delete the plugin and reinstall it. and right now, I cannot even enter into the paypal checkout setup page. That means when I go to woocommerce—setting—payment—paypal checkout. the error shows up, I have no access into the filling live Merchant ID page, directly error page.

I dont a web developper and no any knowladge about the PHP code. someone can help me?

thank you in advance
