Clicking “Customise” in Pacific theme menu producing an error message

Thanks for your help with this issue.

i have two websites that use the Pacific theme, this error occurs on the child and parent theme when activated.

when i click “customise” from the wordpress, Appearance menu, i get this error message:

There has been a critical error on this website. Please check your site admin email inbox for instructions.

the site is running the latest version of wordpress 6.1.1 and the latest theme update.

can you please advise where the problem might be. as i say this happens with the Parent, and the Child theme on two different websites i manage with the Pacific theme.

thank you
