This is a bug that you can report meanwhile you can modify the config file and remove this section from config file and you are good to go .

Hi OP, this is an issue that has been reported multiple times to us: https://github.com/ajnart/homarr/issues/1649. Please do not post bug reports in this subreddit as we do not actively monitor and I’d assume that most people don’t like the reports here either. Thank you!

I removed it via using inspect element and clicking the element in the console, the issue is that the edit icon that is visible when not in editing mode is still overlapping the tile editor when you want to remove it.

1. Open devtools ctrl+shift+i or cmd+opt+i or you can right click on a browser and inspect element.

2. Hit the cursor select button which is the very far left button at the top of the dev tools next to inspector, hover on the element until the entire box is highlighted then click on it.

3. In the div element of the widget, the very first button is the one you want to click, to do so just right click on the button element > choose Use in console option, this will reference the button in the console then just type .click() so it looks like this: temp0.click() then hit enter and the box that pops up to edit tiles will appear and allow you to remove the widget!
