@JamesEdmondsUKPN,Thanks for posting in Q&A.
From your description, I know that you have deployed Microsoft PowerToys via Intune, but get some error about checking app version, uninstalling and updating it.
Based on my testing, I first manually install Microsoft PowerToys from Microsoft store, and then I deployed it via Intune, the Microsoft PowerToys version in my Intune is correct, but I cannot click install and uninstall in Company Portal. Could you please provide us the information how you manually installed the app?
In general, we uninstall app via Intune when we deploy it via Intune. As for uninstalling the app which manually installed on the device, please check if there is uninstall command, if not, please ask app support to get the command.
Moreover, when you deployed app as Microsoft store type, the app will automatically update.
