Hello Danilo. // blind guess ON
You have own custom analyzer's classes build against old Lucene eg mind the package name https://javadoc.io/static/org.apache.lucene/lucene-analyzers-common/7.6.0/org/apache/lucene/analysis/util/TokenizerFactory.html But in 9.4th times they are moved to https://lucene.apache.org/core/9_8_0/core/org/apache/lucene/analysis/TokenizerFactory.html?is-external=true It seems like there's a need to rebuild custom code for the recent Lucene version. Lucene is a core library deployed with Solr, and it isn't judged via <lib> directory. FWIW I suppose it's not possible to bring two Lucene version in Solr.
