There is a mini guide in the DevForum Rules explaining what to do if you find a bug report but are a New Member without posting permissions in that category: Official Rules of the Roblox Developer Forum
See rule 15, specifically 15.1.
Just a friendly reminder that Development Support categories are for getting help with your development work. If you don’t know what category your post fits in, can’t post in a category but have a relevant topic for it or you have any general inquiries, message a Top Contributor (either one directly or the whole group) - they’ll be happy to answer your questions!
