SharePoint Designer issue when creating or opening workflow

Lately I've notice an issue with SharePoint Designer while working with workflows.
So here's what the issue scenario is.
Scenario 1:

• Open SharePoint Designer and then open any site (SharePoint online site)
• Create a workflow for any document library or list
• Below error shows up. 

"Server side activities have been updated you need to restart SharePoint designer."

Scenario 2:

• Open SharePoint Designer and then open any site (SharePoint online site)
• Open an existing workflow
• An error shows up same like above scenario 1.

I've referred many articles online and unfortunately I didn't find any concrete solution which worked for me. So here's what I did and it resolved the issue.

Clear cache from below locations

• %APPDATA%\Microsoft\Web Server Extensions\Cache
• %APPDATA%\Microsoft\SharePoint Designer\ProxyAssemblyCache
• %USERPROFILE%\AppData\Local\Microsoft\WebsiteCache
• C:\Users\\AppData\Roaming\Microsoft\SharePoint Designer

·        

Now uninstall SharePoint Designer
Reboot and then re-install in below order.
