Accidentally deleted disk image folder/ locked folder. Cannot find it or access it now, even though it still takes up space on my laptop.

So a while back I had created a password protected folder by going to Disk Utility and creating a disk image of a folder from there. That disk image file was saved in my Documents folder for long and whenever I wanted to open the locked folder, I had to simply click on it and enter the password. But now I mistakenly deleted that disk image from my Documents folder. So I am not able to access the contents of the locked folder. The folder still exists, I checked Disk Utility and about 14GB of space is taken by "Other Volumes", which I know is that locked folder. https://preview.redd.it/it1ksu0brm8e1.png?width=2338&format=png&auto=webp&s=4137081c87435ed6425bbd7c81910e59a19ac071 But since I have deleted that disk image file I do not know how to access the folder or to open it. Can someone please help me out with how to access it now?
