Best guess for the gray image. If you add a RGB image to either grayscale or indexed then the RGB image takes the characteristics of the destination image. Solution, change the mode of the destination before adding the image Image -> Mode -> RGB
If this happens just opening a single image, must be a MacOS thing. Backup your Gimp user Profile, possibly something like /Users/MyName/Library/Application Support/Gimp/2.10-backup Start Gimp to create a new Default Profile. See if it makes a difference.
The small magenta triangle is an out of Gamut indicator. It means the selected colour is outside the bounds of the color profile chosen. This can be important if the final work goes to a printing company. You can see this if you have color management and soft-proofing active. You can turn all color management off but it is spread across three menu locations, Edit -> Preferences (as shown) , Image -> Color Management , View -> Color Management
