Windows 11 Insider Preview 28000.1 (br_release) - Error message – 0xc1900101
Hi, trying to install the Canary channel Beta 26H1 on my PC, I run into the 0xc1900101 error message. Disk space is sufficient, all drivers are up to date. How can I get this fixed? Many thanks...

Make sure you disconnect external devices while upgrading. Reconnect them once you complete the upgrade.
