Is this the first version of the game you've downloaded? It sounds like it hasn't downloaded/installed correctly. Could you try removing it from your device and trying again? - Hallows
I had another version before that. I'm pretty sure it was the previous version. I've tried uninstalling and reinstalling the hotfix version multiple times and it didn't work unfortunately. (Re-reading the devlog now I realise I was a dummy who didn't need to download this hotfix in the first place because I never experienced the crash.)
Luckily, while writing this reply, I found the .apk file for the version I had previously. I reinstalled that and it works just fine.
Thanks for your time. I'd be happy to answer any troubleshooting questions you have.
