Why was Multi-threading removed?

"Multithreading (experimental)" was completely removed since it was really bad and causing a lot of device specific issues with many people ignoring all the warnings and using it anyway breaking their games just because the setting worked for someone else or even without any reason at all other than having a multi core device.
It will never return in it's old form, currently different, safer MT exists only in Vulkan backend only where it's enabled by default and does not need an option, that new multithreading method might eventually be backported to GL backend, but it will be unlikely to give same results as the broken option, so if you absolutely required that feature on some old device without Vulkan, you might as well continue using old PPSSPP versions on that device.

Why didn't the devs leave the Multithreading untouched? Multithread option causes crashes and break games as we all know. The user can untick that setting instead. Now it looks like the latest version of PPSSPP is exclusively for those Vulkan supported phones, shitty sounds and bad framerate are all that our mid-end devices get without MT option.

Multi-threading option may crash some games.

That trick isn't working for me. Setting CPUCore higher than 1 will make it slower, and even kicking me out from the app.

You should try on of the latest developer builds then. It utilizes a new OpenGL Multithreading code that greatly increases emulation speed and is much more stable than the old method. You'll see speeds that nearly match Vulkan in some games.
