Hey everyone. Thank you for all the info provided !

Just to give you a quick update: our team is already working on a fix for this issue but we don't have an exact ETA for it. As soon as we know more we will come back here with that information 

Can the previous version which 5.89 replaced be made available until such time as the software in 5.89 is fixed.

Also please can you say what Anti-Virus you use on your machine, it would be helpful to the team.

I have the same problem on Windows 10 & 11 all behaving the same, click start, program opens, window appears for a few seconds then closes.

I have/had the premium version. 

I have tried uninstalling and doing a fresh install, trying both the paid version and free version - making no difference, program behaving the same.

I have tried running with the Internet/wifi turned off, makes no difference. 

I have Norton 360 Deluxe version 22.21.11 which is the latest version (auto update enabled)
