Data Cache will not Clear

[EHISAdmin]

I am hitting a "Somehting went wrong" error when trying to clear my data cache in PBI Desktop. I am working in a very large model connected to a SQL DB and some files on SharePoint. I don't dare maually delete teh cache in the AppData>Local folder for risk of messing somethign else up. Below is my attempt to clear teh cache while in a new empty PBI file. 

Help?

@Anonymous I have uninstalled and reinstalled Power BI Desktop and I still hit the same error. Every time I hit the Clear Cache button, I get the "Somehting went wrong" error. I install from the Microsoft Store, so the updates are pushed out, regardless. I need to know where to look fo rhte cache files and which ones to delete to manually clear these, or soem other solutiosn becuase this is stoping almost all my PBI use on this computer.

Hi @EHISAdmin ,

Please make sure you have completely uninstalled the Power BI Desktop, then please download and install the latest version of the Power BI Desktop again, i have test this function in the October version, it works well.

Thanks for your efforts & time in advance.

This is a working solution, but not a pratical one. We shoudl not have to uninstall and reinstall each time this happens
