After a while i decided to move the wallet to a machine with much better specs (i actually use it atm to mine Veil with CPU - Win10 - Ryzen 9 - 16 GB Ram - m2. SSD), no other wallets are running in this current machine and so far the wallet is running smoothly, no crashes, no errors, receiving stakes normally.
i dunno if the above info is helpful but i hope it made the situation a bit clearer for you.
I dont think its about faster CPU and RAM. If you mine your never shutdown neither wallet nor machine, right? Probably this is why no such crashes as was described in my post. As it was already said the problem may lay in the "partial" wallet's shutdown with its process remaining active in background. Nevertheless time is needed to check this assumption.
It doesn't matter if you dont turn off the wallet, it might crash anyway.
At the previous machine the wallet was working 24/7 as well due to staking but eventually it was getting crashed by the same error that you get, although, you're not completely wrong, cause some times it was crashing after reopening when the machine has previously rebooted-restarted (due to updates or whatever).
In the machine i have it running now, in which i both solo mine and stake veil, so far it works ok, this machine reboots as well but so far no issues have occurred.
