Shader '2DxFX/AL/4Gradients': fallback shader 'Sprites-Defaultt' not found

[dearchris]

Hi,

After Upgade to Unity 2020.3.4f1 (64-bit)
I find the unity log has a issue
Shader '2DxFX/AL/4Gradients': fallback shader 'Sprites-Defaultt' not found

Seems Assets\2DxFX\Resources\2dxfx_AL_2dxFX_AL_4Gradients.shader has a typo on it.
