Hello all, today I am using ArcPro for one function of my job for the first time in a few weeks, and I've been puzzled by a very peculiar error/bug that I have not been able to resolve with several hours of troubleshooting today.
Simply put, I can barely use the selection tool for most layers on one of my maps at all. If I try to select one or more attributes (point, line, polygon - doesn't matter) in a large feature class, the application hangs with the "Selecting... Press Escape to cancel" animation showing for an unreasonably long time. On a few occasions its finally pulled up the selected feature after 3-5 minutes, but others I've waited as long as 10 minutes and it can't pull it up. The map appears to draw all of the features fine and relatively quickly, and selecting features in smaller classes isn't really an issue (takes a few seconds when selecting one attribute out of ~5-800 in a FC).
I'm using ArcGIS Pro v 2.9.1 and my PC has fairly decent specifications and everything is running off of a local NVMe SSD that is only ~50% full:
CPU: 8c/16t Ryzen 7 5800x
GPU: RX580 8GB
Ram: 32Gb @ 3200
I'm familiar with the tool lagging slightly and taking a few seconds on large FCs, maybe as much as 10 seconds for a FC with 500,000 entries, but I've never seen it where hangs this bad.
I've tried closing/reopening the application, as well as rebooting. I've saved my map to an *.mapx file and reopened it in a new project, as well as copied many of the layers to a new map in the same project, but nothing seems to help.
I will note that this issue is specific to only ONE map in my project (I have about 5 maps in the project and the behavior is generally normal in others - selection is instant for small FC's and maybe takes a few seconds for large ones). This map is fairly complex with ~50 layers spread across ~10 different geodatabases, and another 10 online ArcGIS Online repositories. The symbologies, and popup displays have all been carefully curated so that I have the information I need at my fingertips by manually selecting features, but no matter what I try I simply cannot select any features without the application hanging.
Just so we're clear, I've checked the selection part of the contents pane and all of my layers are checked to be selectable.
This behavior wasn't always this bad. I was using the same map back in Oct/November 2021 and selections were much snappier. Perhaps this was a change that came about when I recently updated to v2.9.1?
Anyone else experiencing this lately?
