Bugs in content types

I am trying to upload an image to be used as a hotspot background. When it uploads, it does not give me an error code. It only shows the thumbnail with a question mark in it.  I am using the most current version of wordpress 6.1.1 and safari on a laptop macbook pro.

Hello,

When I embed an activity to integrate it into a media, the activity does not adapt to the size of my screen. So I can't see it entirely and I don't even have access to the validation buttons.

This is the type activity "Image Choice"

a big thank you in advance for your responses

1. I have created a slide in the Course Presentation. Then inserted a text. When changing the color, more colors I enter a new color as hex code. After that it crashes, so I can neither save nor press a button. No error message is displayed. Only the screen freezes.
   
2. This happens in Lumi Desktop version (0.10.0 2022-10-26T09:58:44.349Z), Lumi Cloud Version, Moodle Version 4.1)
3. Browser: Chrome, edge
