I updated my site to 8.3 and find that when I create an invoice, I cannot select customers. I get a loading circle on the top center followed by an exclamation in an orange triangle.
This same problem occurs wherever I need to select a customer. For example, under Banking and General Ledger --> Banking Reports --> Customer --> Print Invoices.
I have reverted back to php 7.4, which is the latest version the software runs properly on without errors.
I am running 2.4.18
