After 2 or 3 times, the CTkMessagebox stops capturing the press of the [ENTER] and [ESC] keys.
(I am running on Linux with python 3.11.11)

import sys
from CTkMessagebox import CTkMessagebox
import customtkinter as ctk


class App(ctk.CTk):
    def command_new_message_box(self):
        msg = CTkMessagebox(option_focus=1, option_1="OK")
        response = msg.get()
        print({"response": response})

    def __init__(self, in_app_title, in_geometry):
        super().__init__()
        print(sys.version)
        self.frame = ctk.CTkFrame(self)
        self.frame.grid()
        self.button_new_message_box = ctk.CTkButton(
            self.frame, text="new_message_box", command=self.command_new_message_box
        )
        self.button_new_message_box.grid()


if __name__ == "__main__":
    app = App("test_ctkmessagebox", "640x480")
    app.update()
    app.mainloop()
