This was changed in R-4.4.0:
https://bugs.r-project.org/show_bug.cgi?id=14359

The news item (see news(grepl('paired', Text))) recommends the use of
Pair(x1, x2) ~ 1 instead of the 'paired' argument. A further fix is
currently in R-devel (but not R-patched): without it, Pair(x1, x2) does
not handle the 'subset' argument.
