Yes, we are in a situation today where the real economy may send inflation out of control in some countries. As we were at the early days of covid (but not an year or two later).
I don't know what relation you see between that and UBI.
I think UBI would have a similar effect just via increased demand instead of a decreased supply. When the poor and middle class are all getting supplemental income, and they're competing for the same rentals, the landlords will raise prices, and so on. Same for anything else in limited supply.
