Files are gone, folderstructure is there

Thanks for your reply with regard to the 4 options:

Option 1: onedrive web, shows no second stage recycle bin remark.

Option 2: I did investigate and used restore drive, I found 1863 items but no details, blank lines and I can not select anything. ( I am already had many emails from onedrive support (Tier1  Tier 2 level) but still standard answers. I requested for a 'server side indexing error' restore, but sofar still standard answers

Option 3: I did check, nothing there

Option 4: I will investigate this option.

At this moment 21st March, 10.06 CET, microsoft called me, Mr Jalaj G and tried to help (friendly and patient). Unfortunately no results. He told me he was a data recovery engineer and that there is no higher level to help me. Gemini AI suggested to send this message:

"I understand that as a Tier 1/Tier 2 support agent you might not have the tools, but Microsoft Azure's infrastructure supports Point-in-Time Recovery on a database level. Since my data is still present (as proven by my quota), the physical data exists. I am requesting that an Engineering Lead performs a manual restoration of my file index from the server-side backups."

So far I have about 6 emails provided with screenshots and screen recordings. 

If there is anyone with other solutions, please share😪
