Experiencing an issue with the backend settings

I’m using Events Manager Pro with the Events Manager I/O – Google add-on and it was working fine on my site. Recently when I try to import the events it shows me this https://prnt.sc/XGbza1VfbxKx type of error.

I’m using an updated version of both Events Manager Pro and the Events Manager I/O plugin and my PHP version is 7.4

Can you please help me to look into this?

Thanks
