4.13 was shipped with GHC 8.8 and 4.18 was shipped with 9.6.  See
https://wiki.haskell.org/Base_package

I guess you called "cabal gen-bounds" with ghc version 8.8 in your
PATH but you're now trying to install the library with ghc 9.6 in your
PATH.  The solution is most likely to change the base bound to < 4.20
(so it works with every version of base released so far).

You can avoid uploading a new version of your package by making a
package revision to do this, accessed via the link "edit package
information" under your package's Hackage page.
