Open RBG: "One or more I2C/SMBus interfaces failed to initialize."

Hello and thank you for your help,

I have come across the following error while using openrgb: One or more I2C/SMBus interfaces failed to initialize.
May someone point me to the right direction, please?

This is my i2cdetect -l output

[grnm@gbox ~]$ i2cdetect -l
i2c-0	i2c       	i915 gmbus dpb                  	I2C adapter
i2c-1	i2c       	i915 gmbus dpc                  	I2C adapter
i2c-2	i2c       	i915 gmbus misc                 	I2C adapter
i2c-3	i2c       	i915 gmbus dpd                  	I2C adapter
i2c-4	i2c       	AUX A/DDI A/PHY A               	I2C adapter
i2c-5	i2c       	NVIDIA GPU I2C adapter          	I2C adapter
i2c-6	smbus     	SMBus I801 adapter at efa0      	SMBus adapter
i2c-7	i2c       	Synopsys DesignWare I2C adapter 	I2C adapter
i2c-8	i2c       	Synopsys DesignWare I2C adapter 	I2C adapter

this is my i2cdetect -y -r 1 output

[grnm@gbox ~]$ i2cdetect -y -r 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

Re: Open RBG: "One or more I2C/SMBus interfaces failed to initialize."

I have no offerings for this post except to say I have a similar issue. I've been looking into OpenRGB's github, but I am not good at coding to proffer any solutions (or really understand what isn't working for me or OP).
