I apologize for not responding sooner.  Please configure:

  (setq android-use-exec-loader nil)

reboot your device, and report whether this enables Termux executables
to run normally.  If so, please file a ticket for this to
bug-gnu-emacs@gnu.org with `M-x report-emacs-bug', which generates
valuable metadata concerning your system's configuration.

Otherwise, please attempt to start such programs from an inferior shell
buffer, and see what is printed there.

This cannot be the problem if the OP can successfully execute Termux
binaries from eshell.
