In reply to Sathi.

It's not clear what is happening. You say this happens while reading a large data file, so it's possible that R and/or the R interface ran out of memory. If you are familiar with PowerShell and the Windows logs, you can use something like "get-winevent" diagnostic tool (https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.diagnostics/get-winevent?view=powershell-7.3) and use it to find tkrproxy64.exe entries. You might need to open a ticket with Tech Support and share more details with them.
