Error writing to cloud drive

I installed PA to a cloud drive, pCloud. And a few apps are giving me a similar error message. Most notably the PA platform when I try and close it. A box pops up and says:

Unable to write to P:\Portable Apps\PortableApps\PortableApps.com\Data\PortableAppsMenu.ini

This box cascades on my screen, and I am only able to get past it by invoking task manager and ending the PA process.

Another App that gives me a similar message is FileZilla when I try and close it.

I'm on Windows 10 using pCloud.

Thanks.
