Not sure if this will help similar thing happened to me had 101,000 doge stuck in my wallet dat file from mining in 2014 but my multidoge got corrupted I tried to sync it but it kept getting stuck saying system error while flushing some bs... got referred to some guy who does wallet recovery for lost passwords so emailed them and they took 20% of my doge coins as the fee but I was more than happy to pay because they managed to get in to the wallet in like 12 hours

You can check their website below I spoke to a guy called Adam so try and see if you can get hold of him
