big sur external display missing

I have a MacBook Pro Retina 13" early 2013. One of the two Apple Mini DisplayPorts no longer works. The monitor still works on the other port, but I can no longer have 2 external screens. This happened when I updated from Catalina to Big Sur. Currently have v11.2. Is there any way to correct this issue?

Adding a separate display to my New MBP Interesting issue. I have a Aorus FO48U gaming monitor. I find that when i first connect the MBP to power and then plug in a separate external display (USB-C to DisplayPort) , there is no signal to the monitor at first. I must open the MBP, log into the mac, then the display picks up. Then I can close the laptop and use the display with the MBP lid closed. Not sure why this is happening. My other MacBooks all worked normally by plugging in an external display and keeping it closed provided power was t the MBP. Any ideas? Thanks!! AJB

UPDATE: A full shut down and restart with both external monitors plugged in seemed to resolve the issue.
