Unable to use png's with transparency in virtualbox

So i'm trying to use SikulixIDE 2.0.5 to automate boring and repetitive tasks in a game, in a small virtualbox window to save on system resources and to be able to use my pc whilst the program is running. The original script that i'm trying to downscale the images for works as desired on my pc, however (since want to check if the image is recognised on the device i will be using it on i'm also writing it inside of VirtualBox) when i declare any imported png image in VirtualBox and then click on it, and then click on Matching Preview, the Pattern Settings window freezes for a moment whereafter i receive the following error in the message box;

This error only occurs after clicking Matching Preview, and the window behind/under SikulixIDE is said game, and thus also the canvas to match preview on, not when it's the desktop or browser, but if i check match preview on desktop and then match preview on the game again i will still receive an error every time even if i try to match preview on the desktop or anything else, reimporting the image seems to "reset" this and then i'm able preview on the desktop/browser without getting an error, which isn't what im wanting but it's something. I've searched the internet for hours but been unable to find anything on the issue where i would usually at least find someone with a related or similar problem, and im also relatively unexperienced and unaccustomed to scripting so i was hoping a master of the arts would be able to recognise the problem i'm having here. i mean obviously its the transparency of the image even though i'm not using images with shades of alpha in them, only 0 or max. But i have no clue why the program works flawlessly on my pc but is giving me the error on virtualbox
