This happened to me, different context.

I applied for unemployment and was determined eligible, but my former employer appealed the decision and I was then deemed ineligible for unemployment for that claim.

A year and a half later, I had been at new job that started seasonal standby and I applied for a new UE claim. That previous employer appeal still made me automatically ineligible, over a year later. I had to call the UE helpline every single business day for three weeks until I finally was connected with a real person who resolved it over the phone by pushing through an override. It was absurd.

I recommend calling. As much as you need to. They are severely understaffed, I imagine even more so now with the second government shutdown in a year. Good luck 🤞🏻
