Hi @Allister1
Try the following:
1. Right after the trigger in your flow, add a Select action and switch Map to text mode

2. In the From field add Approvers (not Approver Email)

3. In the Map field, enter the following expression:
item()?['Email']

This will give you an array of emails.
4. To flatten the array into a string, use the Join function

The From field needs to be the previous Select action
The Join with field needs to be a semi-colon
;
5. In the Assigned To field of the Start and wait for an approval action add the the Join function from the previous step

This will not create an Apply to each loop because we are passing a string instead of an array.
6. Test it
