You would be better off posting your questions on the Triangles discord which I posted a link to a page back. You could try this and see if it fixes your wallet issue and that is to back up your wallet.dat file in appdata/roaming. Once you have backed up your wallet then delete all the files but not your wallet.dat and then start the wallet again. It will sync from the start again so it could take a while but see if this fixes the wallet from crashing and not opening as I have had this happen with me on a couple of other wallets. Remember to back up your wallet first which is the most important thing.
