Hey @Angelic_Wizard67f7,
I’m sorry you’re dealing with this right before a deadline. Since you’re using a school account, please first make sure you’re signed into the correct Adobe profile. An Education profile mismatch can prevent your projects from appearing in Adobe Express. See: Profile mismatch in Adobe Express.
Since your projects aren’t appearing in Projects or Deleted, I’d also contact Adobe Customer Care directly so they can investigate the account: Contact Adobe Customer Care. Adobe’s support page provides the option to contact an agent after signing in. (You should be able to ask to speak to an advisor after briefly describing your issue to the virtual assistant.)
If the chat doesn’t open, please disable pop-up blockers and accept Adobe cookies, or try opening the support page from another browser/device.
