It is recommended that you report the error using the feedback hashtag along with screenshots or information that will help developers see what is happening.
I noticed that the link that is created when uploading an image is now different, with a webp extension. Maybe they are testing to make the image playable on all front-ends, i.e. full compatibility.
I tried to upload a screenshot here to show the error, but it wouldn't let me do it.
I am configuring some things, to see if it is my browser or some other problem if this continues, I will create the report again, but this time using the proper tag, thanks for commenting, I hope you have a happy day.
Otherwise you can go to the Discord and mention in the general channel. I tell you this because they will probably tell you to create a ticket, and in my opinion it is faster to let them know directly.
I have already managed to solve the problem, I tried to change some things in the browser and delete the cache, and everything continued normally.
I posted something new on my profile and it did let me upload images, thanks for your help.
