[Bug]: OBS Refuses to Open [segmentation fault]
What happened?
This issue occured completely randomly for me. The snap worked reliably well for multiple months, so am guessing maybe an update screwed something up. After removing and re-installing the snap, OBS studio opens fine, but only once. when the app is closed or the computer shut down it does not re-open. my OS is Ubuntu 20.04.6 LTS I have tried googling this for a couple days and can't seem to find a solution to my exact problem. I'm really hoping to start streaming again soon.
What should have happened?
I should at least get an error message but i would also like the app to run

OBS Studio is software designed for capturing, compositing, encoding,
recording, and streaming video content, efficiently.
**NOTE: This is a community-supported modified build of OBS Studio; please

https://github.com/snapcrafters/obs-studio/issues**
**Batteries included**
The snap of OBS studio comes pre-loaded with some extra features:
* Supports **nvenc (NVIDIA) and VA-API (AMD & Intel) accelerated video
encoding**.
* **Advanced Scene Switcher** plugin; an automated scene switcher
* **Browser** plugin; CEF-based OBS Studio browser plugin
* **Directory Watch Media** plugin; filter you can add to a media source
to load the oldest or newest file in a directory.
* **Dynamic Delay** plugin; filter for dynamic delaying a video source.
* **Freeze Filter** plugin; freeze a source using a filter.
* **GStreamer** plugins; feed GStreamer launch pipelines into OBS Studio
and use GStreamer encoder elements.
* **Move Transition** plugin; move sources to a new position during a
scene transition.
* **NDI** plugin; Network A/V via NewTek's NDI.
* **RGB Levels** plugin; simple filter to adjust RGB levels.
* **Source Switcher** plugin; to switch between a list of sources.
* **StreamFX** plugin; collection modern effects filters and transitions.
* **Text Pango** plugin; Provides a text source rendered using Pango with
multi-language support, emoji support, vertical rendering and RTL
support.
* **Transition Matrix** plugin; customize Any -> One or One -> One scene
transitions.
* **Waveform** plugin; audio visualization using fftw.
* **Websockets** plugin; remote-control OBS Studio through WebSockets.
**Connecting Interfaces**
For the best experience, you'll want to connect the following interfaces.
sudo snap connect obs-studio:alsa
sudo snap connect obs-studio:audio-record
sudo snap connect obs-studio:avahi-control
sudo snap connect obs-studio:camera
sudo snap connect obs-studio:jack1
sudo snap connect obs-studio:kernel-module-observe
**NDI**
If you want to use the NDI plugin you'll need to connect the Avahi Control
interface.
snap connect obs-studio:avahi-control
**Virtual Camera**
Starting with OBS 26.1.0, Virtual Camera support is integrated. Here's how
to install and configure `v4l2loopback`:
sudo snap connect obs-studio:kernel-module-observe
sudo apt -y install v4l2loopback-dkms v4l2loopback-utils
echo "options v4l2loopback devices=1 video_nr=13 card_label='OBS Virtual
Camera' exclusive_caps=1" | sudo tee
/etc/modprobe.d/v4l2loopback.conf
echo "v4l2loopback" | sudo tee /etc/modules-load.d/v4l2loopback.conf
sudo modprobe -r v4l2loopback
sudo modprobe v4l2loopback devices=1 video_nr=13 card_label='OBS Virtual
Camera' exclusive_caps=1
**NOTE!** Using `video_nr` greater than 64 will not work.
**Removable Storage**
To access content on external storage, connect to the removable-media plug:
snap connect obs-studio:removable-media
**3rd Party plugins**
To install pre-compiled plugins, download and extract the plugin to
`~/snap/obs-studio/current/.config/obs-studio/plugins/`.
This is how the Input Overlay plugin looks when correctly installed:
/home/username/snap/obs-studio/current/.config/obs-studio/plugins/
└── input-overlay
├── bin
│ └── 64bit
│ └── input-overlay.so
└── data
└── locale
├── de-DE.ini
├── en-US.ini
└── ru-RU.ini
If you want to use the Input Overlay plugin, you'll also need to connect
the joystick interface:
snap connect obs-studio:joystick
