Issues reloading plugin UI's when having syntax error.

[StealthyExpertX]

I noticed a bug while writing some plugins.

When a plugin has a UI error, you undo your changes to the plugin that caused the issue,
you no longer able to reload the plugin with the reload button after all other plugins' UI's will no longer display correctly.

1. Create a plugin with a syntax error.
2. Load Amulet in any version.
3. Load any random world.
4. Load the operation that has the error.
5. Notice no UI in the screenshot is rendering for the working plugin "Set LootTables"
6. Try reloading the plugin after fixing the issue in the plugin, it will still not fix the UI rendering bug until you reload Amulet.

Expected behavior is that the reload button would reload the plugins and their UIs. One plugin messing up shouldn't affect all other plugins.

• OS: Windows 10
• Version 8.8

My thoughts on this are that syntax errors/issues shouldn't affect the running of the entire program and cause it to not display the UI correctly for other working plugins.

The error that I saw in the console when it was happening.

RuntimeError: wrapped C/C++ object of type SimpleChoice has been deleted

Example: note this was purposely created to replicate the issue, I duplicated some lines in the UI code and the issue is now present.
