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.
"We have received reports that in particular circumstances the latest versions of ProtonVPN Windows clients might lead to Blue Screen crashes in Windows, due to a conflict with certain antiviruses," ProtonVPN said.
Impacted customers are advised to disable their antivirus to prevent system crashes or to downgrade their ProtonVPN client.
Although ProtonVPN didn't reveal more details about what causes the stop errors, more details were provided in user reports of Windows blue screens caused by the latest version of ProtonVPN that surfaced about two weeks ago.
This is not the first time users have reported experiencing blue screen crashes on their Windows computers while using ProtonVPN. At the time, customers in comments [1, 2] added to a ProtonVPN support article on Windows connectivity issues that their systems would crash after authentication or after establishing the VPN tunnel.
Update February 05, 08:26 EST: The ProtonVPN 1.18.5 stable version has been released earlier today with a fix for the reported Windows blue screen crashes.
