text-icu-0.7.1.0 has text < 2 but GHC 9.4 comes with text-2.0.1. Thus, building text-icu-0.7.1.0 with GHC 9.4 should fail already at the constraint solving phase (and does so with cabal). That it is anyway attempted in your case is likely caused by stack ignoring bounds.

This is a non-issue, I suggest to close it. Not sure how you got there; if at all, this is an issue with stack.

Oh yes, my bad! Thanks
