Error Raised during long export

I am trying to export a sequence in premiere using pymiere, and it's chugging along nicely until after about 3 minutes, I get the following error:

I'm not sure what to make of it. Does premiere become non-responsive during export to whatever protocol is being used to query it? Is there a relatively painless workaround here, or a way to explicitly re-establish communication?

Idk if you still need it but i made a simple workaround :

• Create a never ending loop
• Write "pymiere.objects.app" -> this will check if a connection can be established, if not, return an exception. Because it returns an exception when failed, which is something that would end the loop, you need to write it inside an "try" block
• At the end of the "try" block, you return to quit the loop and the function
• at the exception you could write any function that tells you the connection wasn't made

import pymiere
import logger # could switch logger functions for print()

def check_if_premiere_alive(TIMEOUT=2) -> bool: # Returns True if connection is established
            is_first_check = True
            while 1:
                # Loops infinitely til Adobe Premiere Pro communication is re-established
                try:  # (pymiere.objects.app) will return an exception and end loop if no conection could be established, so try is necessary, i guess?
                    pymiere.objects.app
                    logger.info("Adobe Premiere Pro connection estabilished") # No exception was returned, which means that a connection could be established (Video finished rendering/Premiere has open)
                    return True # Ends loop
                except:
                     if is_first_check == True:
                         # Connection error message. Will only show once to avoid spam
                         logger.error("Adobe Premiere Pro connection couldn't be established, maybe the program is not open")
                         is_first_check = False
                 
                time.sleep(TIMEOUT) # Possibly unnecessary delay?
