Hi Nadia,
I understand you wanted to recover from what I check, In general, it is only possible to recover a deleted Minecraft world under specific conditions, and if none of those conditions apply, recovery is not possible. The reason is that Minecraft worlds are stored as local files, and once they are deleted and overwritten, there is no built-in way for Minecraft to restore them.
If the world was deleted today, recovery may still be possible only if one of the following applies: the world still exists in the system Recycle Bin (for Windows), the folder was included in a backup solution such as OneDrive backup, or a manual copy you created earlier, or the deletion occurred on a server that keeps its own backups. In these cases, the world folder can simply be restored to the Minecraft saves directory.
If none of those backups exist, then recovery is not realistically possible. Minecraft does not store worlds in the cloud, Microsoft accounts do not back up single-player worlds automatically, and there is no official recovery mechanism. File-recovery tools sometimes claim to restore deleted data, but they rarely work for Minecraft worlds because the data is made up of many small files that are quickly overwritten by normal system use. For that reason, even professional recovery attempts usually fail once the save folder is gone.
