What's the problem

I can not paste an image from clipboard, which outputs the following errors:

index.e9b7d4f516d61d3c8942.js:209 Uncaught TypeError: Cannot read properties of null (reading 'type')

The edit panel doesn't show anything. However, I found it works fine in Firefox (in the same OS).

Current behaviour

Screenshot (optional)

Provide steps to reproduce:

1. Screenshot an image with ctrl+shift+printscreen
2. Paste it to the edit panel
3. See error

I encountered this problem even it is a blank note.

It was a killer feature why I'm using hackmd. Please fix it.

Hi guys, We have investigated this issue but can't reproduce it. Could you let us know where and how did you copy the image into the clipboard?

[morm]

Hi, thank you for quick response. In my case I can't upload image even with the "Insert" button.

I managed to paste image from alt+prtscr but failed by Copy image in Chrome browser

The problem seems to be solved after I reinstalled the Chrome. @morm maybe you can try this method?
