I have this persistent on going issue where I'll mindlessly hit a hotkey by accident and then all the addons I have installed will disappear in the n-tab menu before I even notice. The addons are still installed and are functional, but I can't access their tab menus as it just blips out of excistence every so often. The n-tab menu will only have the default tabs like tools, view, and edit.
Below I put a picture with the retopoflow, which has it's own menu and buttons at the top; this tells me the addons are working and installed. Sometimes, the tabs will reappear after hitting random hotkeys or will just be there when I reopen blender after a long time. Everytime I try googling this issue, there's no information on this it or I get redirected on how to install an addon or troubleshoot it. If I unistall, and reinstall the addons, it will come back onto the n-tab menu for a moment, but then disappear after working for a while or if I close out blender.
I had this problem with ver 2.8, 2.9 and now 3.6.1.
Is this some sort of bug, or is it a hotkey I'm not aware of?
