i hope you retrieved your research articles, today i have the same problem, and contact with the RG help center & waited their response. i wish it solved and restore the research pages.
Unfortunately, you can't do anything about that. Kindly upload the articles again. The number of views will start over again as if it is the first time u upload them.
I already did the same mistake with an abstract proceeding, I lost 600 views and the system start as if it is the first time uploading. However, the number of citations will not be changed even if you deleted the papers. That's great news for you I think.
