ProjectSettings/ProjectVersion.txt is missing m_EditorVersio

Error message

ProjectSettings/ProjectVersion.txt is missing m_EditorVersion

What it means

GetUnityVersion scans the whole ProjectSettings/ProjectVersion.txt for a line starting with m_EditorVersion and falls through to this error when no such line is found at all. Unlike the empty-value case, the key is entirely missing, so no version could be extracted.

Solutions

1. Verify you are in the Unity project root that contains a populated ProjectSettings/ProjectVersion.txt
2. Restore the file from version control or regenerate it by opening the project in Unity
3. Manually add `m_EditorVersion: <version>` to ProjectSettings/ProjectVersion.txt
4. Disable the unity segment outside real Unity projects

Example fix

// before: ProjectVersion.txt missing key
ProjectVersion: 2022.3.10f1
// after
m_EditorVersion: 2022.3.10f1

// verify the key exists before enabling the segment
data, _ := os.ReadFile("ProjectSettings/ProjectVersion.txt")
hasKey := strings.Contains(string(data), "m_EditorVersion")

When it happens

Trigger: Enabled calls GetUnityVersion in a directory where ProjectSettings/ProjectVersion.txt exists but contains no `m_EditorVersion:` line — an empty file, an unrelated file, or a file whose keys were renamed.

Common situations: Empty placeholder ProjectVersion.txt in a stub/scaffolded directory; Unity version upgraded to a format the reader doesn't expect; checking out a repo where the file was committed blank; being in a lookalike folder with only some Unity settings files.
