The site is experiencing technical difficulties.

Hello,
After I have updated Woocommerce to the latest Version, I got a crash on the checkout page, I have disabled Woocommerce Multi Currency and my website worked fine.

I have tried to delete Woocomerce Multi Currency and upload it again, but my website give the following error:
“The site is experiencing technical difficulties.”

please find the attachment which contain the setting I have previously used.
