Roman, apparently you have TL 2020 installed. Since we are not equipped
to support or debug old versions, I advise you to replace your
installation with the current one, 2022, and try again.

Also: the included perl is intended just to support the TL
infrastructure. For other uses, you are on your own.

By the way: tlshell is a Tcl/Tk script, serving as a front end to
the Perl script tlmgr.

Although tlmgr has a GUI mode of its own, using Perl/Tk, the Perl/Tk
module is not part of the included Perl for Windows anymore.
