Windows Powershell Not Opening

Greetings, I am a new member on this forum and I need some help. Actually a few days before I installed Windows Powershell. The first few day I had no longer any issues while opening the app. But since last day, when I tried to open the app, Windows can’t find the app. I dont understand what could be the issue. Could someone please help me fixing the issue?

After not getting any response, I started searching online and found some articles like this one. I followed some useful methods from there. First I run SFC Scan and updated Windows Powershell. After doing the tasks properly, the problem got solved. Now I have no longer any issues while finding the Powershell app from my PC.
