Garmin 66SR abandoned me the night before a trip

As always, I connected my Garmin 66SR to my Windows PC to create a route with BaseCamp. After uploading it, the screen suddenly started glitching.
Here’s what I’ve already tried:
Hard reset
Soft reset
Deleted the route
Deleted everything again with a hard reset
Unfortunately, nothing worked. I’m pretty frustrated since I won’t be able to bring it with me tomorrow.
Does anyone know why this is happening, or if there’s a possible fix?to take it with me. Any suggestion on why this is happening and how to fix it?
I'm using an original garmin cable connector.
