Hi CC,
First of all did you customize any code? If no, then deactivate all the plugins that you have installed in your dashboard and then check it. If the problem still persist then
try to upload your image from the logo uploader. Before clicking on “insert into post” Check whether you have selected none or File Url or attached post Url
Select File Url. View this screenshot

Hope this may help you

Thank you!
