Do I have a case for unemployment?

My new supervisor doesn't agree with me politically outside of work. I cannot prove this, but we saw each other at a park and I was wearing a mask but she was not. It was cordial but after that work got worse.

I had an outstanding performance for 5 consecutive years with documentation. I met over 100% of the quality metrics consistently and received two raises.

She became my supervisor two weeks ago. Last week, she wrote me up for attendance that happened before she was my supervisor. There are 10 total late attendances spread out over the year, the most recent being in July. When I was with my previous supervisor, we discussed each one and none of them were penalized or documented. (Computer performing an update, power outage, things outside my control).

They switched to a new system. In the new system, everything is disorganized and does not work properly. The broken system has been acknowledged by the department manager, IT on multiple occasions, and four supervisors. It affects several employees. Because of the broken system, I am not able to meet the 100% metric daily and my total overall performance has dropped an average of 6%. It is a terrible number but I am trying my absolute best.

Both write ups happened on the same day. She is giving me another write up today for an unknown reason.

Also: I recorded one of our meetings where she sabotaged my work. (For anonymity I will change minor details). I do not have the details of the assignment or locations, she was providing everything new to me in the Zoom meeting. She told me I needed to complete files and assign them to Florida. So she and I both waited in the meeting while I worked on the task with our mics and screens on. I completed the files and assigned them to Florida, then she started saying they were done incorrectly because I did not assign them to specific codes in Florida. She mentioned my performance but I corrected her saying she watched while I was doing the assignment and didn't say anything. I did not know about codes because I was never told. I asked for the codes to each file and redid them.

Please help. Do I have a case or am I out of luck?
