## Environment
Joplin version: 2.10.2
Platform: Windows 10
## Steps to re…produce
1. Double click any pdf to open it in the built in pdf viewer
2. Close the pdf via the X in the top right corner
## Describe what happened
The pdf should be closed normally. Instead Joplin crashes fatally. All plugins are disabled.
This post describes the same problem on macOS: https://discourse.joplinapp.org/t/pdfviewer-crashes-on-exit-click-the-x/28775
