looks like node is not able to open some files. Can you check if it exists at all.

The persistence node docu says:

Remark: The message regarding flows:started should be fixed by DeanCording in his node, but he has not released a node-red package yet.

I reinstalled node red, from the flow I removed persist node, did deploy then installed persist node and things were fine. Strange work.
Thanks to everyone who responded. Greetings.
