How to pass string with backslash at end to json_query

Below is the JSON output text from a command, trying to fetch FullName and FileVersionRaw where FullName not contains '\msvc\\'

```
{
"windows_result.output": [
{
"FullName": "E:\\\\app\\\\client\\\\product\\\\client\\\\bin\\\\file.txt",
"Mode": "-a----",
"Target": [],
"VersionInfo": {
"FileVersionRaw": "19.0.0.0",
"ProductVersionRaw": "0.0.0.0"

}
},
{
"FullName": "E:\\\\app\\\\client\\\\product\\\\msvc\\\\vc10\\\\file.txt",
"Mode": "-a----",
"Target": [],
"VersionInfo": {
"FileVersionRaw": "19.0.0.0",
"ProductVersionRaw": "0.0.0.0"

}
}
]
}

```

Below code produces result as we search only for string '\\\msvc' which starts with backslash

```
- name: Print result - Windows
debug:
msg: "{{ windows_result.output | to_json | from_json | json_query(client_path) }}"
vars:
client_path: "[? !contains(FullName,'\\msvc')].{FullName: FullName, FileVersionRaw: VersionInfo.FileVersionRaw}"

```

Result output:

```
"msg": [
{
"FileVersionRaw": "19.0.0.0",
"FullName": "E:\\\\app\\\\client\\\\product\\\\client\\\\bin\\\\file.txt"
}
]

```

However if string modified to '\\\msvc\\\\' to search msvc between backslashes, \\' at end considered as escape for single quote and throws error. Please help.
