Why does my python program start another instance of itself at a button click?

Every time I click a button in the app I am currently working on, the program goes to "no response" and then launches another instance of itself while the old one is still active. I don't know how or why because while having it run inside the IDE it works. As soon as I pack it with auto-py-to-exe, it does this.

The code for the Button:

info_but = customtkinter.CTkButton(menu,text="", font=custom_font,          
                                image=info_def,bg_color="#FDF6E4",fg_color="#FDF6E4",hover_color="#3b444b",
                                width=70, command= info_menu,height=70)
info_but.place(x=20, y=220)

The function getting called:

def info_menu():
    global update_label, gpu_label

    stop_thread()
    # Beispielverwendung
    os_ver = f"{uname().system} {uname().release}"  # get_gpu_models()

    threaded_check_for_new_version(repo_owner, repo_name, current_version)

    proc_info = cpuinfo.get_cpu_info()

I fixed all errors the IDE threw at me when I clicked the button like thread handling and such, but still no luck. I also changed the names of the variable and function because I noticed that I (stupid) used the name multiple times for different things..

stop_thread is NOT the culprit since it was added AFTER the error occured.
