I tried to follow your advice by first uninstalling the existing Tk::Canvas with the command cpanm --uninstall Tk::Canvas, and then reinstalling it with the command cpan Tk::Canvas. Uninstall was successful. The installation failed with messages ending as follows.

This does look familiar. I think that I did have this problem with my original installation of Tk, but do not remember the solution.

UPDATE: Found my old notes. Refer Tk install fails. I had installed Tk with the command cpanm https://github.com/StrawberryPerl/Perl-Dist-Strawberry/releases/download/patched_cpan_modules/Tk-804.036_001.tar.gz. Perhaps I should uninstall all of Tk and repeat that command.
