Not being able to save a document

[BlueriteSoul]

Summary

I just want to be able to save the document (ctrl+s), but hitting this shortcut literally does the opposite -> undoes any changes since last save. Strangely, even if I do File-Save, it does the same thing. Is this intended behaviour?
Possibly related to: #24643

Steps to trigger the problem:

1. open a document
2. make some changes
3. hit ctrl+s or file-save
4. zed undoes all changes

Actual Behavior:
undoing unsaved changes
Expected Behavior:
saving changes

Your keybind looks fine.

Do you have a formatter configured in your Zed user settings (~/.config/zed/settings.json) or project settings (.zed/settings.json)? Can you paste the relevant lines? (note formatter can be defined both globally (a bad idea) and under the languages.WhateverLand (a good idea).

A misconfigured formatter combined with format_on_save can trigger odd behaviors. Zed expects custom formatters to be configured to read from stdin and write to stdout and not directly touch the filesystem. See more here: https://zed.dev/docs/configuring-zed#formatter

Does it save correctly if you run workspace: save without format from the command palette (ctrl-shift-p)?
