USDC in 5 accounts is 'stuck'

Ticket # 16447, 164234, 164153. I allowed a scammer into my trezor T when I responded to a number labeled "Trezor support. After taking crypto the scammer said USDC was ‘stuck’ and couldn’t be extracted. I see USDC in my Trezor wallet, but have not been able to move it, exchange it or trade it. Is anyone versed in the process to “un-stick” USDC?
