What exactly are your system specs?
Did you use syscoin-4.4.2-win64-setup.exe or syscoin-4.4.2-win64.zip?
Windows 7 is too old and Syscoin not guarantied to run there anymore.
Why did you install Visual Studio to run Syscoin?
After that assertion error, the program is in a state where it can't do a proper shutdown anymore, so the possible symptoms will appear.

Hello

sorry for late response. I run different different setups.

What exactly are your system specs?
I have tested on different systems, intel i7 core 4930K and i5 4590 with each Windows7, Windows10 and Windows11.
Always the same result.

Did you use syscoin-4.4.2-win64-setup.exe or syscoin-4.4.2-win64.zip?
It doesn't matter which version.

Windows 7 is too old and Syscoin not guarantied to run there anymore.
I know! To reproduce the issue its always a good thing to try on every systems and parameters.

Why did you install Visual Studio to run Syscoin?
While I needed it to program I also installed VS to check if the failure occured again. I give it a try but nothing helped.

I came to the conclusion, that if you create an empty legacy wallet then the failure will occure.

How to produce:
Create an empty legacy wallet without scripts and import privkey.

How to solve the issue:
Create a legacy wallet (HD wallet) and import privkey.

"Create an empty legacy wallet" means a wallet without HDseed. This function is only meant to be used to set the HDseed yourself instead using a generated one. After the wallet has the HDseed set, it will work normal.
This is pretty much BTC standard.
Importing a priv key (like other wallet functions) needs a full functioning wallet, which means a wallet with HDseed
