It seems like you did not deploy solr properly in tomcat.

@MICHAEL TUFFOUR did you find any solution to your issue? I am having the same problem. Regards,

Maybe your solr index is corrupt or locked by .lock file. Maybe delete

C:\dspace\solr\search\data\index\

and try to create new index with dspace index-discovery -b
