"Your workspace has exceeded the 1GB limit..." despite the small size workspace

I get the message "Your workspace has exceeded the 1 GB limit and has been placed in read-only mode. Learn more about upgrading your plan and checking storage usage" despite the small size workspace. 

My workspace size is about 660Mb https://prnt.sc/tP4nRMCF8BNu

Could you help to run garbage collection for me please? 

Thanks
