In Chrome I suddenly got error when any key is pressed while I am inside of Odoo or webpage that is created using Odoo (even on odoo.com)

This is the error:

Uncaught TypeError: Cannot read properties of null (reading 'CodeMirror')
-- URL of database/page --

Traceback:

TypeError: Cannot read properties of null (reading 'CodeMirror') at :75:30

Clearing cache reopening chrome etc didn't help - this happened on Chrome 108.0.5359.124 (Official Build) (x86_64) - both on Mac OS 12.6 and on Windows 10 (I'm not sure what is the version of Chrome but fully updated and with same account opened using same extensions).

I suspect some of my extensions was causing this error so I turned them all off and started to turn on one by one and check if error shows up again. It didn't but I guess disabling and reenabling extensions somehow helped so if anyone has same problem you can try this

I found out that this extension is causing problems: Blackbox - Select. Copy. Paste & Search

Disable it to get rid of this error.

Try to open Odoo in other browser without any addons installed. I got this error few times and problem was always with one of the addons.

I tried, cleared cookies, removing addons but it throws the same error...Which addons could be responsiblw?

In my case it was "Blackbox - Select. Copy. Paste & Search". There was another one but I forgot the name - addon used for font inspection. Other than that I don't have any other idea you could try, ofcourse try in another browser (Firefox, Safari, Edge...)

OK...thanks Matija, I will try
