When you have system update there is this warning:

Warn about old perl modules
WARNING: '/usr/lib/perl5/5.34' contains data from at least 1 packages which will NOT be used by the installed perl interpreter.
 -> Run the following command to get a list of affected packages: pacman -Qqo '/usr/lib/perl5/5.34'

After searching you see it’s caused by

$ pacman -Qqo '/usr/lib/perl5/5.34'
perl-term-readline-gnu

So this package should be rebulded, because in repositories is perl 5.36
