I cannot access the log file as Citra won’t open. When I go to AppData - Roaming, there is no folder for Citra where I could find the log.

Do you have Windows 10 N edition? You can check what you have if you open for example dxdiag (do a simple for it search near Start).

If you do then you simply need to install the Media Feature Pack from Microsoft. The N edition of Windows 10 does not come with it by default.

Unfortunately that did not fix the problem.

I downloaded the media feature pack but when I check dxdiag, it still says my OS is Windows 10 Home N 64-bit

That is normal, you have a special edition of Windows 10.

Which pack did you install? 32-bit or 64-bit? x64 is 64-bit.

The missing .dll file is related to Media Pack as MF stands for Media Foundation.

I installed both packs, neither changed the error message.

Which Windows 10 N version are you on? You can check this by going to your Windows search bar and typing in winver. Open the prompt that pops up. It should tell you your Windows 10 update version.
