Why does the translation fail after 2000+ features enter though TopologyBuilder as input??

hello, I am currently running fme build 2019.1.0.0 and I am having trouble figuring out the exact cause of my "translation failed". I believe the translation fails when more than 2000+ line feature enter the "TopologyBuilder" transformer. I am working on a new computer and I updated to 2019.1, so i am unsure if it is a bug or, perhaps, I have something within system environment that is tripping-up FME Desktop.

I am trying to find the longest path of a Three-Phase Electric Line (overhead & Underground primary) to the substation feeder (dynamicprotectivedevice). Ideally, I want to manipulate the data so I can find the longest line by tracing upline from point-feature (dynamicprocteivedevice) to the end any line segment that doesnt have line features on both end. This is the first workspace of this nature I have created, so I am not too sure how to approach it. I use the topolgybuilder to find vertexes that are the end, and have no connection. I narrowed it down to topologybuilder as the source of error.

It may be due to some error or inconsistency in the input geometries. Have you tried inserting a GeometryValidator before the TopologyBuilder? In particular, make sure to check for basic integrity:

No I did not! Nevertheless, it still did not work. Thank you though, @david_r. My workaround was to convert the GDB into a shapefile, which worked but I would have preferred the gdb due to .shp attribute length and field restrictions.

Although this transformer did not correct anything, it did lead me into the direction to find that .gdb data was source of error as it was corrupt.
