Hi Sagar Agarwal,
The 40352 error usually occurs when an antivirus program or firewall has blocked an executable that it doesn't recognize.
To verify this, create an exception in any antivirus or firewall application for both Tableau.exe and TDEserver64.exe. Then re-launch Tableau. If the ability to create or edit exceptions is not available, the local IT team should be able to assist in configuring this.
Please let me know if this was able to resolve the issue, or if the error persists.
