Core showing a lot of instability

Hello,
I have a device with Android 15 and I'm trying to play games like Conker's Bad Fur Day, but the core crashes or is very unstable, and when I try to restart it freezes, which doesn't make sense because a few weeks ago I was completing Ocarina of Time and it was (almost) perfect.

My specs are Dimensity 8300-Ultra with Mali-G615 MC6, OpenGLES 3.2, and Vulkan 1.3 (two extensions (something storage 8 and 16 bit) are missing).

This core hasn't had any changes in quite some time. Two months since the last commit, in fact.

Isn't the Android core stuck at 2020?
