Unable to decrypt a file in Nextcloud

Nextcloud Version 25.0.2
OS - 6.1.1-1-MANJARO
PHP 8.1.13
nginx version: nginx/1.22.1
mysql Ver 15.1 Distrib 10.9.4-MariaDB
Installed App - Default encryption module - 2.13.0

I have raised a request earlier with no solution hence opening the request again -

I have a couple of files which I am unable to open

I am getting a pop up error - “Load file fail! An internal server error occured.”

If I go into Logging I get the following error message -

[no app in context] Error: Cannot decrypt this file, probably this is a shared file. Please ask the file owner to reshare the file with you.

GET /apps/files_mindmap/ajax/loadfile?filename=Me%20Myself%20%26%20Irene.km&dir=%2F
