A follow-up story about Phison investigating the issue in SSD controllers has also been published: https://wccftech.com/phison-acknowledges-ssd-failures-on-win...

One of my family members has a Beelink SER8 that stopped successfully booting Windows 11 Pro after the August 2025 update. A Windows pre-boot screen shows saying there was a problem, but none of the troubleshooting and rescue options work to get it booting again. The only option left is to reinstall Windows. It seems like an SSD failure, just like how these articles are reporting.
