That's a problem in the embrac package following a recent update of the
fontspec package. See:

https://groups.google.com/d/msg/comp.text.tex/h8Jl4fqaF9E/RDx8zM0dCgAJ

The embrac maintainer should have been made aware of the problem, but
I'd say it cannot harm if you file a bug report at
https://bitbucket.org/cgnieder/embrac/issues

Re: "LaTeX3 Error: Command '\textsi' not yet defined!"

One final note:  I have discovered that if I go to TexLive and change Configure 
> Change Default Tex Live Version from "TeXLive-2019" to "TeXLive-2018", the 
error and the "L3 Programming Layer" messages disappear.  I hope that narrows 
things down sufficiently.

David,

Additional details will be useful to folks if they wish to help.  For example, 
what versions of LyX and TeXLive were being used "before" and "after"?  What 
version of macOS were you using before and after?  Perhaps most important: 
please provide a minimal working example (MWE) 
[https://wiki.lyx.org/FAQ/MinimalExample] that demonstrates the problem now 
(and, ideally, that used to work before).

Thanks for the report, Paul. Can you post the output from reconfiguring
LyX? It seems that we check to see if your TeX installation allows
spaces or not while reconfiguring. (if interested in seeing the source
code, grep for 'tex_allows_spaces'). As for why the change, it could be
because when you installed 2.3.4.2 you also installed a newer version of
your TeX distribution. Or it could be a code change in LyX, but since I
can't reproduce it's hard to know.

Best,

Scott

Aside: It might also be a (new) incompapatibility with some other package
which would be solved by commenting out the other one...

More probabely, one updated package (embrac, one of its dependencies or some
other) now uses the LaTeX3 syntax in LaTeX2e package (expl3.sty or so)
which generates the error. Looking at the first line(s) of the LaTeX log
will show the used LaTeX version.

A minimal example would be helpfull there as well as here...

Re: "LaTeX3 Error: Command '\textsi' not yet defined!"

[David Pesetsky]

Thanks.  Is there a way to stop LaTeX3 from compiling the file?  In fact, 
independent of using or not using this package, since starting to use Lyx again 
a day ago, no matter what I compile, I periodically see the message "L3 
Programming Layer " on the status bar at the bottom of the Lyx window.

Lyx 2.3.4.2
MacOS Catalina 10.15.3

This is pretty suspicious. It suggests, to me, that LaTeX3 is being used
to compile this file, which will almost certainly cause major problems
with LyX. Then again, it's possible that the problem is just local to
the embrac package. You might try writing the maintainer at
cont...@mychemistry.eu.
