[Bug]: App Fails to Open Last Library on Startup and Segfaults on Directory Refresh

Checklist

TagStudio Version

Alpha v9.5.5

Operating System & Version

Pop!_OS 22.04 LTS

Description

Intro

Apologies if these are two separate issues. This is my first time installing this program, so I got them simultaneously. I also want to make sure I express that this program is really unique and a great idea, and I look forward to using it, as there is nothing quite like it. Thank you for your effort in developing it. Perhaps when I have more free time I will try to contribute with some pull requests.

1st probem

On launch, the application consistently fails to open the last used library and instead displays an error dialog stating "Path does not exist. open_path=None".

This occurs even though the configuration files in ~/.config/TagStudio/ appear to be correct.

• settings.toml has open_last_loaded_on_startup = true.
• TagStudio.ini correctly lists the path to the last used library (/home/guga/Documents/2ndBrainMedia).

The configuration files are being read, as changes made in the GUI (like date_format) are correctly saved to settings.toml.

2nd problem

More critically, and I don't know if this is related, clicking the "Refresh Directories" button causes the application to crash immediately with a Segmentation fault (core dumped).

Context

These issues occur consistently under the following conditions:

• Using either the portable or the non-portable version.
• Running the executable from any location (~/Downloads, ~/, /usr/local/bin).
• With all listed dependencies confirmed to be installed.

Expected Behavior

On Startup:

The application should read the TagStudio.ini file and automatically open the last used library (/home/guga/Documents/2ndBrainMedia) without displaying an error.

On Refresh:

Clicking "Refresh Directories" should trigger a scan of the library files and update the view without crashing the application.

Steps to Reproduce

Startup Error

1. Ensure a library has been previously opened so its path is saved in ~/.config/TagStudio/TagStudio.ini.
2. Launch the TagStudio application from the terminal.
3. Observe the "Path does not exist" error dialog appears.

Segmentation Fault Crash

1. Launch the TagStudio application.
2. If a library is not open, open any library.
3. Click the "Refresh Directories" button in the UI.
4. Observe the application immediately closes, and a Segmentation fault message is printed to the terminal.
