[Python] Python threading blocked by keyboard library?

While building a script that can be toggled to spam, I encountered the following problem.

First is the normal functioning version of the script:

import keyboard
import threading

def spam_this():
status = 0
while True:
if keyboard.is_pressed("F9") and status == 0:
status = 1
event.wait(1)
if keyboard.is_pressed("F9") and status == 1:
status = 0
event.wait(1)
while status == 1:
if keyboard.is_pressed("F9") and status == 1:
status = 0
event.wait(1)
print("test")

event = threading.Event()
threading.Thread(target=spam_this).start()


The script above works perfectly. However, when I change the line print("test") to keyboard.write("test"), the script breaks.

import keyboard
import threading

def spam_this():
status = 0
while True:
if keyboard.is_pressed("F9") and status == 0:
status = 1
event.wait(1)
if keyboard.is_pressed("F9") and status == 1:
status = 0
event.wait(1)
while status == 1:
if keyboard.is_pressed("F9") and status == 1:
status = 0
event.wait(1)
keyboard.write("test")

event = threading.Event()
threading.Thread(target=spam_this).start()


This version of the script with the keyboard.write() function can be initiated with the implemented toggle key "F9", but when I try to toggle off the switch by pressing "F9" again, it does not stop like the print("test") version of itself.

Note: I am not sure how to word this problem in the title. I use the term "blocked" because the effect is similar to what blocking method like time.sleep() would do when trying to create a while True: loop with a toggle.
