Photos not deleting - 'Recieving end does not exist'

[Calorian]

I have a list of 38 duplicates that I'm trying to delete. The popup opens as expected but they each fail.

The error is as follows
service_worker.ts-72f4954d.js:1 deletePhoto message error, retrying (retries left = 1) Error: Could not establish connection. Receiving end does not exist. D @ service_worker.ts-72f4954d.js:1 service_worker.ts-72f4954d.js:1 navigateAndDelete error Error: Could not establish connection. Receiving end does not exist.

Any ideas what I may have missed or done wrong?
