XPS 8700, boot issue, error message 0xc0000098

Dell XPS 8700 with the i7-4790. Good specs for gaming and upgradable still. First problem in at least over 5 years. Now getting error message 0xc0000098 and it won’t boot into Windows 10 anymore. 🤦‍

Thank you for any help you can give. I already tried scans, diagnostics, etc.  The ePSA Pre-boot System Assessment says all is good?
