latexindent: Unknown PerlIO layer 'encoding' - Formatting failed with exit code 255 macOS 12 Monterey

Question

I try to run latexindent under macOS (12.0.1) from Visual Studio Code (1.63.0) with the LaTeX Workshop plug-in ( v8.22.0 ). It doesn't work because an error occurs during formatting.

I have already installed these cpan packages:

• Log::Log4perl (1.54)
• Log::Dispatch::File (2.70)
• YAML::Tiny(1.73)
• File::HomeDir (1.006)
• Unicode::GCString (2013.10)
• File::HomeDir (1.006)
• Mac::SystemDirectory (0.13)

I also tried to update the CPATH environment variable with this command

export CPATH=/Library/Developer/CommandLineTools/SDKs/MacOSX12.0.sdk/System/Library/Perl/5.34/darwin-thread-multi-2level/CORE:$CPATH

This also did not work.

The Perl executable is in this folder: /opt/homebrew/bin/perl . I have the version v5.34.0 . I have already read this latexindent: trouble installing File::HomeDir, Mac::SystemDirectory since macOS 11 Big Sur .

Can someone give me some hints on how to solve this problem?

Here is the error output:
