I feel for you @frozenlychee, if your wallet shows coins on the blockchain then it would be worth borrowing access to a computer of someone you know and install daedalus on it and restore your wallet on that computer just to find assurance that you still have access to your coin’s, you could then print them out onto a paper wallet or just know you still have access to them.
I have found problems over the years with all sorts of software, sometimes it is a problem with the computer I use it on, maybe a program installed by the seller I bought it from, maybe something I downloaded, in any case I am very confident in the blockchain that holds your ADA and if you have your seed words to restore your wallet you will be fine, unless precaution was not taken to protect your investment.
The community will certainly assist you with known problems if you could give us something to help direct you to the fix, if it is a new problem then there is no doubt in my mind that you will get a response after submitting your logs, 2000 dollars is alot of money and will not be overlooked by all of those involved with Cardano.
If i were you I would clean my computer program files up and delete everything that I did not ever plan to use (I would actually have to verify all programs I kept were actually legit) , I would wipe my RAM clean and be sure to erase everything that I had concerning Daedalus, then I would restart my computer, download Daedalus, restore my wallet by using my seed, and if that did not work then I would use another person’s computer to get my money back, or I might search the forum here for similar experiences and try what they say worked… In general from the post’s I have read - if your wallet holds the coins on the blockchain and you have the seed words you will be able to recover your ADA, again I feel for you, and I hope you the best.
This is like a tattle tale of a sorts that would tell me that something is wrong with my computer.
