The screen goes black without errors still can hear the player can move, and it remains the same even after restarting the game (creative mod).

THANK you all, I tried the last release and I managed to find the psi-client.toml file, the following change:
useShaders = false
and it WORKS!

Log, Psi version, Forge version and what other mods are you using?

In the psi-client.toml file in your configs folder set useShaders to false.
I think it might be a shaders issue.

sorry but the problem still occurs even after setting "Use Shaders" =false (in the psi.cfg file, I don't have psi-client.toml).
are there any dependencies should I download OR try to remove?
Thanks.

How do you not have a psi-client.toml file? Psi or any forge mod for that matter, does not use .cfg files on 1.15.2

I use TLauncher 2.69 with Minecraft Forge 1.15.2.

• Psi version : Psi r1.2-79
• other mods: [Bountiful_3.1.1, jei_6.0.0..4, Kottle_1.5.2, tl_skin_cape_forge_1.10, Xaeros_Minimap_20.11.0_Forge]
  debug.log
  latest.log

I installed the game from scratch and still have the problem.

I can't find the psi-client file under config .minecraft/config folder.
once I get the CAD in inventory the screen goes black, and apparently there are no exceptions in the logs.

Had a similar problem with the configs (both common and client) not being generated for some reason. Fixed in #593 so once that change is released you can try disabling shaders.
