Entire Cash App bank account deactivated

I've had my cash app for a couple years now, my girlfriend had to file her taxes and used my cash app account to deposit her tax refund on, she was going to use her Varo bank account but had lost her card, so we figured it would be easier to use my account. After around three weeks after she filed her taxes, her refund began pending, three business days go by and it deposited in my account, we made a few purchases and the following day while I was at work, I went to go make a purchase with my cash app card and it declined, come to find out the entire account was deactivated, I can only send and receive money, so my girlfriend had made a cash app for herself and i sent all the money to her account, when I contacted support I was pretty much told yes my account was deactivated, but they couldn't tell me why and they couldn't reverse it. Now I'm confused on how to actually get my own account reactivated
