Spouce not eligible to apply for an ITIN according to IRS Interactive Assistant

I am a US citizen (and British citizen).  I am domicile in Britain.  I married a UK citizen in 2022 who has no SSN, TIN etc. She is only a British Citizen, ....period.

My wife has no income to report t the US yet my form 1040 asks me for her SSN (or ITIN)  since I am now filing as "married - separate".

I am not eligible to get a ITIN for her, according to the IRS Interactive Assistant as she is non-USA; non-resident in USA and has no USA income to report.

I wish to file an exemption for her but to do this, apparently I need an ITIN for her.  I seem to be caught in a loop. 

What should I do?
