From Adobe:

Dynamic Submission Quotas (Weekly Limit & Pending Moderation Limit):

• Adobe Stock has implemented updated submission limits to maintain collection quality and manage the volume of content, especially with the rise of generative AI submissions.
• These limits are not a fixed number for all contributors. They are dynamic and based on several factors related to your account's performance and history, including:
  • Your weekly submission limit.
  • The maximum amount of content you can have pending moderation (in review).
  • Your approval rate and sales performance—a higher acceptance rate and more sales can generally increase your limit over time.
• When you reach either your weekly limit or the maximum number of allowed files pending moderation, you will experience a temporary pause before you can submit more content. The limit resets once the pending files have been reviewed or the weekly period resets.

Your account is either new or not very active. Adobe is telling you exactly what to do, my best advice is that you use the wait time focusing on shooting more and what you’ll be uploading next.

Patience is a virtue!
