Since about 3 weeks I regaularly crash my Win 10 with a blue screen with a PAGE_FAULT_IN_NONPAGED_AREA (HipShieldK.sys) error. Thought I had fixed the problem 2 weeks ago by completely uninstalling Thunderbird and re-installing it, but NO. Today I crashed my compi again. This is completely unacceptable, as emailing is essential during COVID-19 and I will not afford a 2nd new compi just because the former rock stable email program Thunderbird is not working stable anymore. Any ideas how to fix this problem? Any help is very appreciated. As I'm considering leaving Thunderbird for another, hopefully more stable programs, any suggestions? A new mail program MUST have an import ability to get more thousands of archived emails in! Thanks for every helpful advice.
