unable to add image source in GRIP

[handsomeadi]

I just opened GRIP and selected "add image source", but some exceptions occurred and there appeared a box telling me that my image was invalid. Worst of all, the app crashed after I closed the issue box. Does anyone know how to solve this?
p.s. Below is the message I got from the issue box.

The image selected was invalid

Stack Trace:

Hi @handsomeadi,

I'm wondering if this issue has anything to do with the 機研 characters in the path of the file. Do you have any way of attempting to load the file from a path that doesn't contain chinese characters?
You could try doing this with an external zip drive.

I'm going to guess that this is because of some sort of issue in openCV unfortunately.

GRIP/core/src/main/java/edu/wpi/grip/core/util/ImageLoadingUtility.java

Lines 28 to 36 in f789fb2

	public static void loadImage(String path, final int flags, Mat dst) throws IOException {
	checkNotNull(path, "The path can not be null");
	checkNotNull(dst, "The destination Mat can not be null");
	final Mat img = opencv_imgcodecs.imread(path, flags);
	if (img == null || img.empty() || img.isNull()) {
	throw new IOException("Error loading image " + path);
	} else {
	img.copyTo(dst);
	}

I'm having the same issue with a path containing an accented character. (Eg : "D:\photos\2021\école\45132747_DB0766.JPG")

A workaround is to replace the accented character.
