//custom logo plugin
function pageLogo(editor) {
editor.BlockManager.add("logo", {
label: `<div className="gjs-block-label"><img src="https://i.ibb.co/nL2Q7WN/logo.png"></div>`,
content: `<span><img src="https://i.ibb.co/nL2Q7WN/logo.png" /></span>`,
category: {
id: "logo",
label: "Logo",
open: true
}
});
}
useEffect(() => {
const editor = grapesjs.init({
container: "#editor",
storageManager: false,
blockManager: true,
plugins: [pageLogo]
});
setEditor(editor);
}, [dispatch]);

I ran into this problem, too. It seemed to happen whenever I started dragging a block's media icon instead of the block text or block container. It seems that the issue was resolved by adding pointer-events: none; to each of my block's media image styles.
The image I'm talking about being dragged:

In my case:
editor.BlockManager.add('lx-button', {
label: 'LiveX Button',
media: `<img style="width: 32px; height: 32px; filter: invert(0.75); pointer-events: none;" src='https://www.svgrepo.com/show/368574/button.svg' />`,
category: 'LiveX',
content: `
<div class='lx-button normal'>View Details</div>
`,
})
pointer-events: none; is not working for me, I literally have to restart the whole browser in order to make it working normally again.
