Windows 11 DISM and repair install failing

[injust]

Background: The system is an XPS 15 7590 laptop running Windows 11 Pro. At some point, it began overheating uncontrollably (fans maxed out, CPU temp reaching high 90°s, etc.) even when idle. The issue doesn't occur on a fresh dual-boot install of Windows, so it has to be an issue with my current Windows install. Windows Defender Antivirus (offline scan) also doesn't work (nothing happens when "Scan now" is clicked).

What I tried previously:

• Replaced the motherboard, heatsink, and fans
  • Also thoroughly cleaned the insides
• Disabled all non-Microsoft services
• Updated the BIOS and drivers

sfc /scannow exits with "Windows Resource Protection did not find any integrity violations."

Dism /Online /Cleanup-Image /RestoreHealth exits with "The source files could not be found"

• Dism /Online /Cleanup-Image /RestoreHealth /source:WIM:D:\sources\install.wim:6 (index #6 for Windows 11 Pro on the mounted ISO) exits with the same message
• Dism /Image:C:\ /ScratchDir:C:\ScratchDir /Cleanup-Image /RestoreHealth /Source:ESD:D:\sources\install.esd:6 when booted into the ISO off a USB flash drive produced a useful log file (will upload soon)

SFCFix did not detect any corruption

Windows 11 repair install (following Repair Install Windows 11 with an In-place Upgrade Tutorial)

• Hangs on the first reboot (at the black screen with the Dell logo, the loading indicator freezes and I have to force power off)
• Error code: 0xC1900101 - 0x30017
• Tried this several times with external devices unplugged and non-Microsoft services disabled
• There is plenty of available disk space

Dism /Image:C:\ /ScratchDir:C:\ScratchDir /Cleanup-Image /RestoreHealth /Source:ESD:D:\sources\install.esd:6 when booted into the ISO off a USB flash drive produced a useful log file (will upload soon)

Never mind, the log entries I was looking at were also captured from in-Windows DISM runs.

Bumping this just in case it was missed. Please let me know if there's any additional info I can provide that would be helpful.

Apologies no one was able to get to this on time. Due to the high volume of requests, and limited number of volunteers, sometimes a thread gets missed.

Closing the thread as per report.
