Unable to see new cards. Manjaro x64

[ghost]

Whenever I try to see new cards an error appears. Sometimes I'm allowed to see the front of the card but not the back but almost always it won't even let me see that. Reviews are fine and don't show any errors whatsoever. This is the error: Anki 2.1.28 (97eadb78) Python 3.8.1 Qt 5.14.1 PyQt 5.14.1 Platform: Linux Flags: frz=True ao=True sv=2 Add-ons, last update check: 2020-05-21 12:26:23 アドオンが関連している可能性があります：⁨MorphMan for Anki 21, Web Browser - Search terms Import texts and images automatically, Review Heatmap⁩

Disabling Review Heatmap and Web Browser as suggested to be possible culprits doesn't seem to solve the problem. I get this error: Anki 2.1.28 (97eadb78) Python 3.8.1 Qt 5.14.1 PyQt 5.14.1 Platform: Linux Flags: frz=True ao=True sv=2 Add-ons, last update check: 2020-05-21 12:26:23 アドオンが関連している可能性があります：⁨MorphMan for Anki 21⁩
