Describe the problem/error/question

i came back to my projects after updating to 1.117.3 and all credentials are gone. all my workflows are still there.
so i tried to create new credentials and it seemed to work first (green and saved) but when i execute the workflow i m getting the error message like “supabase node does not have access to the credentials”.
Same with all other credentials, OpenAi, Gemini, Qdrant…whatever.
ChatGPT says i have to “share credentials” in settings of n8n (?!?).
When i close the workflow and go back e.g. to my supabase node, the credential is gone again. it didnt saved anything. same in the OpenAI Node and all others.

What is the error message (if any)?

error message like “… node does not have access to the credential”.

Please share your workflow

simple workflow, every node
