All media suddenly dissapeared. Oneplus 5

[jimmyju]

Hi there.
I have a Oneplus 5 running Android 8.1.
Today I connected this to my Windows PC via usb cable to copy over my pictures. After I deleted a file which I believed to be called thumbdata. or similar from my pictures folder (on the phone in the android file structure) suddenly and instantly all kinds of media is missing of my phone.
The folder Pictures, Movies, Music, Downloads, DCIM and probably some other have completely disappeared. The folder Whatsapp is still there but all subfolders with Media, Backup, Databases are emtpy.
The phone storage basically only contains the folder android (all app including cache seem to be working, prime video downloads are still in there too)
and the folder WhatsApp with all subfolders there but empty.

Can you please help me to explain what happened there.
All input appreciated.

Kind regards
jim

Thank you. Unfortunately no actual solution. Still hoping though.
