Salesforce Fact #690 | Approver doesn't have record access
In order to approve/reject a record, the approver needs to have at least READ access on the record. We can create a screen flow to override the standard 'Submit for Approval' button to handle the scenario where the approver is manually selected but the approver does not have any access to the record. The submitter is notified so that he can select another approver or provide record access to the selected approver. In this example, the Account object has been considered. Attached are the screenshots.
