ProtonVPN is working on fixing a bug causing Windows blue screen crashes affecting customers using the latest versions of the company’s Windows client software. The BSOD crashes don’t affect all users and are caused due to conflicts with antivirus software solutions. Blue screens are triggered immediately after launching the VPN’s client software on Windows computers. Customers are advised to disable their antivirus to prevent system crashes or to downgrade their client to the previous stable version. A beta version has been released earlier today with a fix for the reported crashes.
