Animal Crossing: New Leaf Welcome Amiibo can't scan QR codes for Pro Designs

Hi! so I’ve been playing ACNL: WA for a while and I’ve unlocked the sewing machine at Sable Sisters, but the camera feature to scan QR codes doesn’t work (I have an app to use my phone camera on my pc, it’s iVcam), so I have to upload a still image in order to be able to scan a code. However, with pro designs is another story, because you need 4 codes, and the program doesn’t let me upload 4 different codes. I want to know if it’s possible to upload different images or another way to activate the camera?

Issue:
Unable to open the camera feature on Citra Nightly

Here’s some issues I found with your log that might help.

^ This driver is out of date. To update, download win64_15.40.5171.zip from Intel® Graphics Driver for Windows* [15.40]

Mirror link: https://downloadmirror.intel.com/30196/a08/win64_15.40.5171.zip

Then follow this guide to install it: https://www.howtogeek.com/343287/how-to-fix-the-driver-being-installed-is-not-validated-for-this-computer-on-intel-computers/

Furthermore, because your iGPU has driver bugs, you’ll need to disable Accurate Multiplication in Emulation>Configuratrion>Graphics>Advanced tab to prevent graphical issues from occuring.

As for your QR Code problem, make sure that you have the right 3DS camera configured in Citra’s camera setting. Some games require the back camera for certain features and the front camera for others. By default, the front camera is configured, so you might have to change that depending on which camera the game requires.
