Mouse operation becomes ineffective after registering an item

After the update, when I register a product using this plugin, the item UI remains displayed and I can no longer use the mouse. I can use the keyboard, but the interact key and other controls don't work either.
It seems like I'm stuck there because the UI remains displayed.
Please check.

Sorry, I can't take video, so these are screenshots.
After registering the item, when you open the vending machine, the UI shown in the photo will remain.
Buttons such as the mouse, interact, and enter key (chat) will no longer work.
You can still move around in AWSD.

Since my server only uses economics (item: paper, skinid: -1779183908),
I had changed "currencyType": "Economics" to the above item,
but I found that removing 「"currencyType"： "Economics"」 in the latest version causes the symptom shown above.
The quickest way to reproduce this issue is to remove all currencies except scrap from "Default currencies to show when opening the currency list."
This didn't reproduce  in previous versions, but people who don't use other currencies may make the same mistake again...
