Elasticsearch 7.9.3 fail to start

Hello,

I'm trying to install Elasticsearch 7.9.3 but when I'm trying to start elasticsearch I get this error:

Can someone help me debug this issue?
DO you know if this path should be clear /data/dnc/data/nodes/0/indices before I install the elasticsearch (I have some old files that are from the other elasticsearch version, maybe I have to clear the /data path in and install it again)?
I mention that on this path /data/dnc/ was another elasticsearch version running but I wanted to uninstall it and try to install here version 7.9.3

Yes it does.
