Understanding why I have 0 for buying_power

A few weeks back I was at a balance above 25K and able to day trade as normal. I fell below this after SEC fees put me just under that level. Since then I have only been showing 0 for buying_power and have sold off only some on a few up days during this turbulent time. I don’t think I am under any sort of restriction but I am not sure how to read if I am in my /v2/account get request (below).

I plan to hold on to my balance for now while I wait for the V, but I am also wondering if I will be able to restore my buying power If I were to sell all. I come from robinhood so things are not as clear as was used to.

Very much appreciate any insight into this so I know what to expect.
