Since today morning I've been having an issue with the components panel. I've been working on a file for months but, for some reason, the components panel won't show/load all of the components. It looks like as if it's a memory problem that won't load the whole file.
Also, when I create new components it won't show up in the panels. I've tryed reinstalling, creating a new project, installing on a different PC with no sucess.
We are sorry to hear you're facing issues with layers and assets panels. Would you mind sharing the screenshot of your about XD info page? I would also request you to please try signing out of XD and sign back in.
