Is my SD card garbage?

I have a Samsung J6 smartphone and on Christmas I got a new 32 GB memory card, and that's when my phone started to break down.

My gallery where I put my pictures and files started to become inaccessible where they were all blank. There were files there, but I couldn't access them.

When I try to reboot my phone, it will shut down but it wouldn't restart even when I hit the button. I only got it to restart when I pulled out the battery, waited 10 seconds and put it back in. After that my files became accessible again.

I even reformatted the card as well, not a quick format, but a long thorough one. And it seemed to work until this morning where it started to go haywire again to the point where I couldn't even access my banking app or Facebook.

I looked it up and my phone can handle a memory card of 128 GB. And I have an older 1GB SD card that I had inserted before and it hasn't given me any trouble whatsoever.

So is my SD card garbage or is there another explanation?

A case of I would like to know before I restore my phone or shell out more money on a new SD card.
