Downloading and installing the main x86-64 version of Anki listed on the https://apps.ankiweb.net site causes an immediate segmentation fault. The suggestions from Segfault on startup - #11 by danko and Segfault when trying to start Anki on Linux - #8 by jetri do not fix the issue for me. I’m running on SteamOS:
