Merge tool in ArcGIS Pro Slows Performance

I've been combing the forums for a while now, reading up on the topic of slow performance in ArcGIS Pro. For reference, I'm on the most current version (2.4.2) and I'm editing data in a 10.6.1 geodatabase running on SQL Server 2016.

 

Has anyone noticed performance issues specific to the Merge tool? My current project involves a lot of chopping up and merging polygons into new configurations. The other tools that I commonly use (Copy Parallel, Split, Explode, etc) perform normally. When I select the Merge tool, I immediately start seeing the blue circle of death as Pro tries to bring up the panel. Even after I've done the merge and continue on with other tools, the performance is sluggish until I hit the back button on the Merge tool and go back into the Modify Features pane. While I'm working with fairly large polygons (1/2 mile to a mile long, maybe 66-80 feet in width), there aren't really any curves or excessive vertices in the geometry that I would expect to cause a slow down.

 

I've been tempted to call tech support, but I wanted to see if anyone else has experienced this first.
