looks like you got the same error as me, if u read some posts before i made a tutorial. you need to disable real time antivirus scanner and add "webchaind.exe" to the exception rule. it is a bit complicated because the webchain wallet block the webchaind.exe. if u have real time scanner active.. so make sure u turn real time scanner off while running webchainwallet.exe as administrator..after your webchainwallet updated webchaind.exe you should now make the exception rule for you antivirus firewall while your real time scanner is deactivated, after you done the exception rule u can enable real time scanner again and wallet will work fine.
if you still have trouble come to their discord channel in "general" or "mining" chat.. we will help you
