Google Drive Desktop Version - Loss of numerous folders with very important and historical data

Re: Your Google Support enquiry [***]

I submitted a query on 17 January 2022 regarding the new Desktop Version of Google Drive, and have yet to receive a response. I'm extremely dissatisfied with the lack of service, and especially the amount of folders on the web version of Google Drive that have disappeared (some of which had more than 20 years' of files). When I accepted the invitation to download the Desktop version I understood that the folders on the Drive would remain, and that the new application would be used solely for back-ups and syncing. I quickly discovered that my desktop doesn't have sufficient space to use for this purpose, so I tried to uninstall the application. However, it keeps on re-launching and using up disk space on my desktop, which is preventing from me to be able to continue with my work. I purchased additional space on the Drive Web version so that I could store data safely there, and there is still a significant amount of space remaining. I need urgent resolution in rectifying this matter, and recovering all the lost data that disappeared.
