Uncaught TypeError: Cannot read property 'value' of null

[finnock]

I very frequently get this js exception, resulting in an "infinite loading spin" and the editor crashing.
Reloading the page sometimes works, sometimes doesn't.

Browser: Chrome 78.0.3904.97 (newest to date)
OS: Win 10

main.js:86 Uncaught TypeError: Cannot read property 'value' of null
