I thought you had tried different op-amps from your assortment?.
Obviously changing the pin arrangement.
Did you try testing them?.
I don’t think you are reading all replies.
If the circuit worked for a bit on breadboard, it must be connections.
Try not to be sensitive, push the connections in!. Terminate them... Plug it in and and check while wiggling connections. Breadboards are good but also known for bad connections. Be a brute and push, wiggle while checking.
