ArcGIS Pro: Polyline Symbology error: "Requested operation could not be completed"

[ElieRizk]

The issue persists in AGP 3..3.1 it is a show stopper to work with complex symbology for polyline layers. we are not able to move forward with such behavior. it is noted, the issue faced when using a feature class stored in file geodatabase and enterprise geodatabase.

we tried the steps mentioned in the following ESRI technical support page without success.https://support.esri.com/en-us/knowledge-base/error-requested-operation-could-not-be-completed-00002...

Also, someone mentioned that ESRI categorized this issue as a bug, but we aren't able to find the bug number.

"@ABishop kindly can you head up to the number of the bug mentioned in the URL you inserted in your message?

Here is a link to the BUG report site: https://support.esri.com/en/Search-Results#search?q=arcgis-pro&content-type=Bugs"

I had this a few weeks ago. 
Could not figure it out and have not had time to lodge a bug; but did lodge a few Ideas.

All I can say is unless you specifically use 3.3 functionality just revert to 3.2/earlier.

I am having this same issue. Apparently it has cropped up in several ArcPro versions. Sure be nice to get this fixed.

sorry for being late in replying.

I solved this issue by using unique value symbology with auto-generation (list all values) and then changing the symbol for each value separately. that's worked for me.

I can confirm this same behaviout with lines but It's also happening with polygons.  I don't seem to be able to modify or add composite symbols in an existing pre v3.3.1 layer. (anything composed of more than the 2 default symbol layers). The only solution seems to be to add the layer into the map and build new symbology from scratch. When I get the "Requested operation could not be completed" warning, i am not able to same the symbol or layer symbology.

I'm having the same problem with point symbology. I can't apply any complicated/multi-layer symbols from the gallery. Adding a second layer to a basic point symbol and then trying to choose a more complicated symbol from the galley sometimes works. Both the error and that workaround are not consistent.

I have this same problem for a line feature. I have multiple complex line symbols I'm using for a set of trails in a local park, and I need to change some of them symbology wise. Now, I can't change anything and will be time consuming to re create this in a new layer from scratch.
