Fatal error: Unparenthesized `a ? b : c ? d : e` is not supported. Use either `(a ? b : c) ? d : e` or `a ? b : (c ? d : e)` when setting local WP

Question

So I am in the middle of hosting a live wordpress site locally using XAMPP. The code is in a bitbucket repo and I have been given the database from the staging site to connect my local environment.

After renaming the database with the localhost links and cloning the repo, these errors popup when trying to access the WordPress back-end.

the code for the respective errors in respective order of the screenshot are as follows:

Help with this would be appreciated. Please let me know if anymore details required

Try to use PHP Version 7.4 Possibly a plugin you are using does not support newer versions than 7.4
