If your spouse has zero days present in the US for 2025, has no US sourced income and has informed the USCIS/ IRS that her visa is to be cancelled, then I see no reason for her to file a US return. If you two do wish to file as MFJ, ( and her J-2 is not cancelled) then you can treat her as a resident but expose her world income to US taxation. ( Generally though that may require her to be temporarily absent from your tax-home).
Is there more I can do for you ?
