Bitcoin found in old harddrive for Bitcoin Core

Hey guys i have recently found my old harddrive down in my basement and when I opened it I managed to find a folder with alot of videos photos and personal files and I managed to find something very valuable. My fathers wallet was in my personal files because back then we only had 1 computer which was shared among our family. My father sadly passed away in 2017 and the wallet has fallen into my hands and it has alot of bitcoin in it (I won't disclose how much bitcoin, but it's REALLY valuable). I have let the wallet sync for about 2 1/2 weeks now and sadly its stuck at 88% and doesn't seem like it wants to move, any Idea on what I should do?

The wallet is MultiBit HDI have the information such as the seed and passcode.

I hope I can get some help from here.

EDIT: Thank you all for the feedback and support on this thread. I wanted to disclose something alot of people have been talking about in the comments. No, I am not begging for attention nor am I lying, I am simply trying to gain access to this wallet but, it has been solved ever since someone commented and told me about storage as blockchain takes up alot of space. Because, I was using a 256gb HDD which half of it was used up and since it's a HDD it explains the sync being super slow. I have moved the files to a 512gb SSD and hoping this syncs.

Thanks!
