“SQLDeveloper.app” fails to open after upgrading to Big Sur

I recently upgraded macOS to Big Sur and now I can't open SQLDeveloper.app. I am getting this message: > SQLDeveloper.app can’t be opened because the identity of the developer > cannot be confirmed With macOS Catalina it was working perfectly. A similar question was discussed here https://apple.stackexchange.com/questions/177168/sqldeveloper-app-can-t-be-opened-because-the-identity-of-the-developer-cannot . I already followed the approach mentioned there, but that did not solve my problem. Any pointer towards the solution would be highly appreciated.
