Loss of access to files in the storage

I downloaded Cryptomator, created a folder in it called private, which it hid when closed, put my files in this folder, after some time in the private folder I created a few more folders, and then decided to rename the private folder itself to a different name, when I did this, I lost access to the files that were inside this folder. The program gives the following answer - Content unavailable
The folder contents could not be displayed due to an unknown
error. The files are very important, I urgently need to access them
