Kingston 5300t thunderbolt SD stops working after upgrading to Mac OS 12.3.1

I have a Sandisk extreme 1TB. I was able to access it via Kingston SD5300t thunderbolt 3 port before the upgrade. After the upgrade, I can't anymore.

To be fair, I am able to access it if I hook it to my M1 Macbook Air directly but I will be left without any other port if I do that. Obviously, this might be an incompatibility between Kingston SD5300t thunderbolt 3 port and the new version of Mac OS.

What gives? Is there a plan (for Apple or Kingston) to fix it?

This may be a false alarm. After a few hours, the blue light on Kingston SD5300t lit up. I then plugged the SD Harddrive back into the thunderbolt 3 port and it is working as before.

I am not sure why it will do this though.
