Can't paste images in Discord web-app

Something happened with my Discord tab in Chrome. Before I was able to copy image (not URL) and paste it to chanel. Now I can't... And dunno where is the problem. Drag'n'drop - working properly. "Insert file" button - working properly. Paste in Discordapp - working properly. Tried to reinstall Chrome and use Incognito mode, but it doesn't help.

BTW paste in web-app in Chrome at my work - still works fine.

Where to dig?

PS sorry for my english.
