Hi,
I have a number of PBIX files that return an error message I don't understand when opened in the Power BI Desktop "App" version installed from the Microsoft Store, but work fine in the standard installer version.
The specified key is not a valid size for this algorithm. Parameter name: key Key Length: 40
It makes me nervous to install the very latest version but I will have to at some point. In all cases the data is being pulled from a SQL Server instance.
Does anyone know what this error is and how to resolve it?
Thanks in advance.

You could check the Issues forum here:

And if it is not there, then you could post it.
If you have Pro account you could try to open a support ticket. If you have a Pro account it is free. Go to https://support.powerbi.com. Scroll down and click "CREATE SUPPORT TICKET".
For the benefit of Googlers with this same issue, I did indeed (eventually) log the issue with the Power BI support team. The advice given to me was delete everything at the following two paths:
C:\Users\%username%\Microsoft\Power BI Desktop Store App\Cache
C:\Users\%username%\Microsoft\Power BI Desktop Store App\CEF\cache
Doing so resolved my issue where the PQ editor woudn't return anything from a SQL Server database, but I suspect from my own searching on the subject that this error message may present itself in a number of scenarios.
