Hello again,
Thanks to Advantage for finding the work around for the majority of the Shop Closed issues which have been reported in this thread. This has been passed along to the Hearthstone team and they are working to resolve this bug as soon as possible.
For anyone on PC (especially new PCs or fresh installs of Windows) you should be able to download the Visual Studio 2015, 2017, 2019, and 2022 packages for both X86 and X64 from the link below. Afterwards the Shop should be functional in Hearthstone again.
Note that we are still asking for logs for Hearthstone users on Android that are experiencing Shop Closed after the patch. If you are encountering this error on Android, please see the previous post here.
