Fatal error After Plugin Update

Last night, I this plugin got upgraded to version: 7.0.2

Then the functionality broke down in frontend. Screenshot: https://imgur.com/jBQmbAG

Then I tried rollback to version: 7.0.0 – It did not fix the issue.

Then I roll backed to version: 6.11.8 – Now issue is fixed.

WordPress version: 6.5.2

PHP version: 8.2.13

Full error:
