I upgraded to Sublime Text 4 (needed license upgrade though) and my favorite plugin/package stopped working. My shortcut was
CTRL+ALT+J in Windows 10. I know it stopped working since I’m already warned during the installation.
The easy fix was just to disable the package then enable it again.
Package Control > Disable Package > Pretty JSON to disable it.
Package Control > Enable Package > Pretty JSON to enable it again. My keyboard shortcut is still not working but I used a different slightly longer shortcut now.
CTRL+ALT+P then type
json and it should show the shortcut to pretty format json.
