### Please confirm these before moving forward.

- [x] I have tried deleting a folder named `UniGetUI` under `%UserProfile%\AppData\Local\UniGetUI`.
- [x] I have tried reinstalling UniGetUI.

### Describe your crash

Disclaimer: This may be unique to me since I'm running Windows 10 LTSC 2019.

I'm trying to configure a few apps with "Close apps before installing", and trying to enter text in the appropriate field hard crashes UniGetUI.

Steps to duplicate:
1. Open UniGetUI and navigate to the **Installed Packages** tab.
2. Right-click on any package, then select **Package details**.
3. Under **Installation options**, select the **Change this and unlock** button to disable the default options.
4. Select the **Close apps before installing** tab, then select the text field where process names would be written.
5. Press a letter on the keyboard, and the application will freeze for a moment, then crash completely.

Expected behavior:
- Typing in the text field for **Close apps before installing** does not crash the app.

Thank you for UniGetUI, and thanks for reading!
