Post From: Platform Freezing on Startup

This issue started happening again and has gotten progressively worse as using the ESU26 contract freezes the platform after taking all of the prior steps (that worked until another platform restart) at which point I tried them all again and added the ones below.

Steps I’ve tried since having initially had success

-  Start platform in SAFE MODE.

-  Do NOT open any chartbooks/files nor instances on startup

-  Delete ESU26 & ESM26 Historical and intraday chart data files via these instructions
  https://www.sierrachart.com/index.php?page=doc/ChartDataFiles.html#DeletingChartDataFile:~:text=on%20the%20menu.-,Deleting%20a%20Chart%20Data%20File,-%5BLink%5D%20%2D%20%5B

-  Re-connect to data feed

-  Edit >> Delete All Data and download

-  Open a new ESH26 Historical chart via File >> Find Symbol. The new chart opens and loads data correctly. No studies, just pure daily bar chart. Continuous contract is set to “NONE”

-  Change contract to ESM26 via Chart >> Chart Settings >> Symbol. Chart loads correctly.

-  Repeat symbol change process to ESU26 click “Apply All” data quickly loads then platform freezes. Same thing happens if I try to open the ESU26 from "find symbol" directly as well.

-  Other Products (NQ, MES, MCL, CL, MGC, GC) work fine, this seems to be ES only and ESU26 specifically.

I am at a loss, but this appears to be the same underlying issue that initially caused me to post this thread last week.
