I've been using GM Link for a few days with no issue. Then had the following error warnings (pasted below) when importing a few new sprites. The aseprite file and GameMaker project were the same I'd be using previously. Just added two new sprites. Nothing fancy or different than before.
I'm running GameMaker LTS IDEv2022.03.85 which should be the latest LTS.

Sprites seem to be fine, imported as expected but I'm worried something might be messed up in the asset definition files somewhere deep in my project now.
One clue, I did open the details on a few slices in asprite and changed the color for them so they'd be more visible against the grid. I'm guessing that maybe triggered your 9-slice bounding box code or another advanced feature which I guess isn't fully compatible with LTS?
None of my aseprite slices have 9-slice or pivot turned on, could just changing the color on a slice be enough to change how they export?
UPDATE:
I've run a bunch of tests reverting both my aseprite and gamemaker project each time and restarting gamemaker and it's baffling. Even if I don't add any new sprites, just editing the pixels (touching nothing else) for some sprites triggers the error when I update while others are fine.
Also tried a brand new aseprite file and also got the error when just exporting a single slice. A real mystery what's causing this.
