the wallet is the same as the rxmr wallet which is a cryptostealer thats why it synks to 100% then closes or crash but scan it with virustottal or metadefender both show Malicious sand box stuff like 100% Malicious and after i ran the rxmr wallet i had eth and other crypto stole out of my metamask wallets like $350 worth so scan b4 u run or run in vm but both this wallet and the rxmr both closed after reaching 100% synk it steals your keys
Bad luck my friend, but you can notice is the same dev, he is using now cargo to run his keyloggers.
