Is there a list of error codes? I receive an Error Code 400 when I try to save a file.

Google is a good place to begin with error codes. Error codes in the 400 range have to do with web requests. Was it actually "400"? Or "401"? Or "403"? Or some other number in the 400's? What is the full error message? Or you can attach a screenshot of the error. (If you don't know How To attach a file, click the link.)

Exactly where are you trying to save the file? On your hard drive? On an alternate local drive? On the musescore.com website? On some other website?

Are you able to Save other files? How about Save As?

Please identify your computer's operating system and version, and MuseScore's version. You can get all three simultaneously by clicking on Help / About MuseScore from the main menu. Then click the copy button (two pieces of paper) next to the "Revision" number. Paste that into your post.

For future reference, if you click the button I have circled in red on your screenshot, you get a nice little text listing of the important information, dropped onto your clipboard, so you can paste it where you need.

For example:

OS: Windows 11 Version 2009 or later, Arch.: x86_64, MuseScore Studio version (64-bit): 4.5.2-251141402, revision: ac9d3bc
