I recently had problems with GMP too on my AVX (not AVX2) laptop.
They seem to be solved with the most recent beta.
With a fresh install from the install package "j904_linux64.tar.gz
2023-01-24 17:44  3.4M  j904 linux 64-bit" from
http://www.jsoftware.com/download/j904/install/ , I initially got a crash
report when trying x: in jconsole immediately, but that got resolved after
running updateje.sh .
My session log:

jpjacobs@icarus:~/j904$ ./bin/jconsole
   x: NB. this was before running updateje.sh
x:
   x: 100
JE has crashed, likely due to an internal bug.  Please report the code
which caused the crash, as well as the following printout, to the J
programming forum.

So functionally it seems fine eventually; and it seems this would also be
accomplished by doing the install '*' recommended in the installation
instructions.
Maybe there is still an incompatibility between the non-avx binary and
libgmp causing the initial crash? Not an immediate problem for me though.

Best regards,
Jan-Pieter
