Cloning view into new theme causes crash (v5.0.4)

I'm wanting to display a custom footer on the site, so I've cloned the /Views/Shared/Components/Footer folder (containing the footer default view) into my theme, but even before I make any changes to it, the site crashes when opening any page, with the following error:

Controller: Error, Action: Error, Status: 500 (InternalServerError)

Cannot find compilation library location for package 'System.Security.Cryptography.Pkcs'

I can't find any reason for this, as the Footer is currently identical to the original.  Is this a bug?

This is actually a problem in the main branch too - and the same error is produced no matter what view file(s) are added to a new theme.

Can someone at Smartstore provide an update for this please?  Theming is effectively completely bust on the main branch right now!

please try the newest hotfixes, updated yesterday.

Thanks Stefan, but it's still broken.

I've even tried running the code in the main branch (which presumably has even more recent changes/fixes) and it's still not working there either.  It takes 30 seconds to recreate:

Copy Flex theme folder, copy ANY view into the new theme's View folder, set as active theme and reload any front-end page = crash
