Credentials could not be decrypted.

Describe the problem/error/question

I have n8n installed directly via Windows PowerShell.

Today, I tried updating n8n using the following command:

npm update -g n8n
After the update, when opening my workflows, I received the following error message:

Init Problem

There was a problem loading init data:

"Credentials could not be decrypted. The likely reason is that a different 'encryptionKey' was used to encrypt the data."

Could you help me resolve this issue?

What is the error message (if any)?
