Error message when sending the quote form

Good morning ,
until a few weeks ago I had no problems, now every time I fill the quote form I get the message that says to try to fill the from again because there was an error.

I installed https://wordpress.org/plugins/easy-wp-smtp/ and installed a second one just for testing but I’m still having problems.

I tried deactivating all the plugins and keeping only woocommerce, the smtp plugin and yith active but there continue to be problems.

I repeat that until a few years ago everything worked correctly.

Can you help me please?
