Can you attach a copy of the affected world to your report?

How do i attach a copy of the world over here

It was at 1.16.220 i believe i kept my device storage on external and deleted the app to download 1.17 and the worlds were missing 1 year back so i gave up but i found out my worlds were stored in a different folder safely maybe i did that a year ago and i remember when i went to 1.17 update normally and saw the levels below y 0 and deleted Minecraft for the new update i lost it again and my world was 64mb now but now when i place it it's at 0.42 mb and the world display photo is also gone

You can just press option 'Attach files' and upload if from your device, or upload it on any shareable site like OneDrive, Dropbox and paste the link to it in the comments or update your description.
