Continuously demanding a device restart (v25.6)

This week F-Secure Device Protection has continuously stopped working just a few minutes after start on my Win10 machine (all latest updates installed)., demanding a restart. To no surprise - a restart does not help.
Have FSdiag files ready for inspection, but nowhere to send them. Please let me know where to upload them for inspection.

Hello,
You can try reach their Support directly (https://www.f-secure.com/en/support). The options are phone-call or web-chat. During communication, they will either help you and tell you how to solve the problem. Or they will tell you how to transfer fsdiag for analysis (in particular, to understand whether the reasons in your situation are known and are already being worked on, or whether some new details will need to be studied).
But as a general troubleshooting: if the trouble is still relevant and present, you said that "this week" was a start point. Did you notice if any events happened before this? Has any software been updated, or have you installed anything, or maybe made changes to some settings somewhere, or started using a different network, for example.
I tried to accumulate possible 'known' situations in this topic: https://community.f-secure.com/en/discussion/comment/141627/#Comment_141627
Could you try reading to see if any of the things mentioned might be helpful?
Thanks!
