why some apps don't work well in the emulator?

[HPCarnace]

I have the emulator version 2.1.14730 (2023 4 13), but some Applications like VigaG 4.3 (Edwin Córdiba) do not work correctly. On the physical device (mine is Hardware Version D, OS: 2.1.14730) they do work. I have the calculator since May 3, 2023 and I am developing a program called "HPPrime TORA" (about simplex and graph method) with the same problem. The emulator does work with "small" APP programs, such as "Isostatic Reinforcement 1.5" by Herbert Poma (changing the variable names with the "____" character).
I have already restarted the calculator several times, but it does not work. I have also uninstalled it.
