It seems solr version compatibility issue because sitecore 9 and sitecore 9.1 are compatible with different solr version. for solr version compatibility you can review following sitecore solr compatibility chart .
But you can easily resolve your issue by just enabling your compatible solr version,i.e sitecore 9 is compatible with solr 6.6.2 so you just need to open your local services and stop the other solr version(solr-7.2.1) and start solr-6.6.2 screenshot for your reference. then just restart your site it will be working fine.
