issue with hubble-pi camera capture

I have recently tried to install and get working a program developed to use with a telescope. It is called hubble-pi and can be found here. https://github.com/RemovedMoney326/Hubble-Pi
The program runs but when i click the capture button I get this issue. I have reached out to the dev but he has not replied and that was over a month ago. If anyone could assist in figuring out a solution that be awesome.
Im a beginner when it comes to python so be easy. This is also happening on boot up as this is the first thing im doing when turning on my RPI. I am running this on a RPI 4 2gb.
Python 3.7.3 (/usr/bin/python3)
>>> %Run AstroCam.py
Start

picamera.exc.PiCameraMMALError: Failed to enable component: Out of resources

I just hit this same error with another Picamera IMX477 app, and found a fix.
Set gpu-mem=192 in /boot/config.txt, reboot, and 4032x3040 starts working.
This is for Pi-4, 2GB running Buster. Bullseye is a different animal.

Threads with PySimpleGui gives RunTimeError

I have explored using threads with PySimpleGui but quite often the thread terminates
RuntimeError: main thread is not in main loop
I have tried running the "official" demos, forexample:
https://github.com/PySimpleGUI/PySimpleGUI/blob/master/DemoPrograms/Demo_Multithreaded_Long_Task_Simple.py
This gives me the runtime error when I run it locally. However when I run the same demo on trinket :
https://pysimplegui.trinket.io/demo-programs#/multi-threaded/multi-threaded-long-task-simple
It seems to run fine. I am using
windows 10
Anaconda
python 3.8
spyder 4.2 (IDLE)
I have also tried to run outside spyder (IDLE) with the same effect.
Full error message:

Python manage.py runserver error doing Python Crash Course

Trying the python crash course web app project.
Python manage.py runserver is throwing off a bunch of errors
Exception in thread django-main-thread: Traceback (most recent call
last): File

line 54, in wrapper fn(*args, **kwargs
I figured it out actually, but not sure why or how it works, but decided to leave it here in case someone comes across the same problem in the future.
In the urls.py file, the textbook tells you to add
"url(r'', include('learning_logs.urls', namespace='learning_logs')),"
what fixes it is adding this instead of the above,
"path('', include('learning_logs.urls'), name='learning_logs'),"
'''
python manage.py runserver
'''

What solved my problem was: using this line instead of the one from the textbook
"path('', include('learning_logs.urls'), name='learning_logs'),"

Python - Solving command line error for Tweepy

I am trying to use Tweepy to stream Tweets from a developer API. I want to convert this into an SQLite database file.
However, I am getting an unusual error that links to the Tweepy libraries on my computer. I am using Python 3.6.7 (if that might have something to do with it).
Please let me know if you require more information.
In Windows 10 command line:
Exception in thread Thread-1:
Traceback (most recent call last):
File "C:\Users\CONFIDENTIAL\AppData\Local\Programs\Python\Python36\lib\threading.py", line 916, in _bootstrap_inner

self.listener.on_exception(exception)
AttributeError: 'int' object has no attribute 'on_exception'

When initializing tweepy.Stream, you're passing an integer for the listener parameter, rather than an instance of tweepy.StreamListener. See the Streaming with Tweepy section of Tweepy's documentation.

Multithreading frozen in Python Spyder but not command prompt Windows 10

I am running a script inside Spyder that utilizes the multithreading library and the IPython console freezes with the output below. However, running the script using Windows command prompt via 'python quickstart11.py' works fine and generates the proper output.

I've tried adding freeze_support() according to Python doc, which should alleviate the problem, but it still freezes. What is going on?
Windows 10 64bit, Anaconda Python 35 64bit installer.

The problem is in Spyder. The kernel is running in interpreted mode and the addition of "freeze_support" doesn't happend before other things even if that's the intention, because the kernel is already running.
