Upload limit reached

Hi everyone, I am participating in Challenge L2R'24 LUMIR , but when I submit results, I always prompt Upload limit reached, which prevents me from uploading properly. May I ask if there is a file size limit for uploading, and if so, what is it? The file I am currently uploading is 2.2G. Thanks!

You hit the upload limit as you uploaded many large files and did not click save to make the submission. The files are cleared every 24 hours.
