ArcPro 3.4.3 crashing when changing symbology

Shehasmoxy

Hi,

I had thought this problem was resolved but I am experiencing it. I am working with NLCD, and I am trying to load the symbology so I can reclassify the land cover types. Every time I go to load the symbology, it crashes. I have the latest version of arcpro. I even did a clean reinstall. I made sure I am updated to the latest .net Microsoft software ( I am unable to go to a previous version as my computer does not allow me). It looks like I need 8 or later anyway to run 3.4.3).

I also tried clearing my cache, and changing my rendering engine. I am out of ideas. I have an assigment deadline I am trying to meet so any ideas would be useful.

Some additional troubleshooting items to consider:
1. Since you've done an uninstall/reinstall of ArcGIS Pro, try a soft reset of ArcGIS Pro where it makes some registry changes - How To: Perform an ArcGIS pro Soft Reset
2. For your video card, if it's an NVIDIA, you can set it as your primary 3D card for ArcGIS Pro by accessing NVIDIA's control panel (right click on your Windows desktop > NVIDIA's control panel > Manage 3D Settings > Programs settings tab.
3. Update your video card drivers as Dan mentioned.
4. From a related Tech Support case:
a) Change the Antialiasing mode to Fast (default) or Normal.
b) Change the Rendering quality from Best toward Low.
c) Uncheck the Enable hardware antialiasing check box.
d) Change the Rendering engine from DirectX to OpenGL. If this does not lead to a performance improvement, switch back to DirectX.
e) Check the Clear cache check box.

Solved: ArcPro 3.4.2 crashing when changing symbology - Esri Community

Ed's solution was the only one that worked for 3.4.2, but it is worth a look in case your display drivers aren't up to date.

thank you so much. I found a new NLCD symbology file and uploaded that and it worked. So maybe my older one was corrupted? My current problem is the new symbology file does correctly name all the classes on the layer, like barren, deciduous forest, etc. But when i go to reclassify it does not have the drop down for reclass field option. I manually did it using the numbers but what a pain. I am wondering if I am missing an additional symbology file to upload to fix that. My original one must be corrupted, yet it would correctly name the classes and allow me to use the drop down in reclassify.
