Invalid access to memory - _search234_step

2020-09-18 04:02

I locked my screen, came back and connected back to VPN. WinSCP had three sessions open, two needed to reconnect (normal behaviour after reconnecting to VPN). First session reconnected fine, but the second one produced this pop up non stop. I was getting maybe one pop up a second stacking up.
Had to end task to close WinSCP completely.
