Can you give a complete example of the metadata, as shown by "ffmpeg
-i" or "ffprobe" (without "-hide_banner", and without the other ffprobe
options), the JSON output, and what you are expecting, please?

Correct JSON *mandates* that certain characters be escaped, and double
quotes inside the (keys and) values most certainly *must* be escaped!

Assuming a value such as:

This text has "some" quotation marks

the correct JSON is:

"keyname": "This text has \"some\" quotation marks"
