TeX import problem

[john kennan]

Version 2.4.0-alpha3 (February 14, 2021)

Qt Version (run-time): 5.12.9

Qt Version (compile-time): 5.12.9

Python detected: python3 -tt

Apple M1 Max

macOS 12.4 (21F79)

When I import the attached TeX file into LyX and use

Document/View (other formats)/ PDF (pdflatex)

I get the following error message
 \selectlanguage
                   {english}
Selecting a language requires a package supporting it

If I click on the "show output anyway button", I get the attached pdf (with
the word "english" inserted).

Deleting the following line in the LyX file solves the problem
\language_package none
