I have not heard of this personally but one thing to try is do a "save as" for a new *.aprx file.  Close ArcGIS Pro.  Load the new *.aprx. Close ArcGIS Pro.  Does the latency still exist? ... View more

By chance, do you have a web map from your active portal in the Map View?  In reading a Support Case, this was the issue and is identical to what you're experiencing.  The customer readded the web map using the workflow listed here Add maps and scenes to a project—ArcGIS Pro | Documentation, added the feature layer and the flashing was resolved. ...

Three things I saw within Esri Support Services cases was: 1.  Do you have more than 100,000 features in the feature class where the attribute is blinking? 2.  Does your PC meet the requirements for running ArcGIS Pro?  systemrequirementslab.com/client-app?refid=1256&appkey=6D681CD0-BA6C-4B6B-9A82-639759CFD094&requirementsetid=23091 3.  Update video card drivers ...

In reviewing the Esri Support case logged 2/11/26, I do not see a workaround currently in the case documentation.  I understand that this is a high-impact bug to your organization and I wish I had an answer for you.  Although not a solution, I would contact Esri Support Services and have your organization's customer number associated with this BUG certainly.  Again, not a great solution I know, especially with such a large organization, but uninstalling 3.5.x and reinstalling 3.4.x would allow those tools to work again. ...

Okay - digging deeper, I believe this is BUG-000182720 - "Arcade expressions using FeatureSetByName($datastore, ...) fail to validate in layout dynamic texts in ArcGIS Pro, returning the error “Object not found $datastore.”  It's currently under review.  The issue is not reproducible in ArcGIS Pro 3.4 and earlier but 3.5 and above. ...

One way to test if 3.5.5 "broke" the $datastore item is to uninstall 3.5.5 and revert back to 3.5.4 and then retest. For Windows 10, you can uninstall the ArcGIS Pro 3.5.5 service pack by going to Control Panel->Uninstall a program->(top left) View installed updates->then click the ArcGIS Pro Patch 1 (3.5.5) and uninstall.  For Windows 11, MS made it a bit more difficult, see image below: ...

If you go to the List by Editing view in the Contents Pane (left side of the UI), do you see a red exclamation point indicating broken data links?  If so, either remove those layers from the Contents Pane or fix the broken links to the data source. ... View more

@AbuJeriesGIS  - so this has been a tricky one to find!  I found an Esri Community post about this - Bridge feature type and symbology - Esri Community about bridge and culvert symbols that I read about here.  This led me to finding the ERS Homeland Security 2D symbol here - ERS Homeland Security - Overview  I found a point symbol for bridge which does mimic the culvert symbols.  It's a start! ...

Another workflow to consider is to export both the FC and standalone table to CSV's using the Export Table GP tool.  Then link them together in Excel using the Key Field. ... View more

Thank you for the response.  So for my ArcGIS Pro, I created a generalized polygon with 4 lines that cut across the polygon diagonally as I don't know what your map looks like.  See my image below.  I reprojected my data from UTM to Stateplane so we're now in the same units.  So my understanding with this tool is that IF the lines cross over/overlap/extend past the polygon, then the line attribute information is clipped at the polygon border as it were and gives you a proportion of the line attributes "inside" the polygon.  This is why you wouldn't see the AADT sum value being 56532 unless all 4 lines fell inside the polygon.  Mine do not - 68.93% of the 4 lines fall within the polygon so that percentage is multiplied by 56532 to give me a SUM value of 38967.58 AADT sum value.  For the distance (in my case), I get a Summarized Length in FEET of 46848.01764 which is 8.87 miles. Something is off for sure... ... View more

So I tested the workflows using a polygon and line FC with the same attribute field of CUR_AADT and noticed some differences of your screen grabs to mine.  In the Summarize Within GP tool, I have a Shape Unit parameter - I put in Kilometers as I'm using UTM.  Your screen grab does not show a Shape Unit.  Second, the output table for my Summarize Within has a field yours does not - Summarized Length in KILOMETERS - which does show the correct length of lines in the polygon.  See images below: ...

Since you mentioned that this was occuring in a VM, can you change the VM resolution to a different size and see if the UI resets?  If so, then switch it back to the original resolution and try the workflow again.  Is it reproducible or a one-off? ... View more
