The report only includes a stack trace, centered on TMSearcher.java:86 and AutoTMClusterEngine.java:57 and :83 during TCSideRpcInitCallBack initialization. Start by tracing that initialization path and reviewing the project's TM configuration and logs; done means identifying the reproducible cause and documenting the required correction.
