Thanks, @lurch! Should I mark as duplicate? Is there a master case for this? Is it recognized as an issue?

@phillipremaker I don't know, I don't work on Etcher.

The enable-screensaver error is unrelated to what you describe.

Your problem might come from not being able to unmount the disks at the end of the process, hard to tell.

Thanks @aethernet! Any suggestions of how to do a diagnostic around that? I can't tell why the code has decided the flash process had failed.

I got the same issue yesterday on one of my test flash, but I don't have a solid reproduction yet

I'm suspecting it has to do with the OS mounting the drive before the checks are done, but idk yet how to confirm.

@zvin Can I ask you to look at this? This problem seems to correspond to the electron.ipcRenderer.send changing to electron.ipcRenderer.invoke for the enable-screensave and disable-screensaver calls in #3882.

Windows 11 does not handle these calls correctly, and it seems that the error from these calls mistakenly triggers a Flash Failed for ALL Flash attempts with Windows 11 and Etcher.

I'm not sure what the best fix is.

1. Roll back Fixing call to electron block screensaver methods invocation #3882
2. Have ipcRenderer apporpriately disable Windows 11 screensaver.
3. Have ipcRendered recognize that it can't control Windows 11 screensaver and suppress the error
4. Have the error process recognize that an error from the screensaver is not a flash failure.

Not knowing the architecture of the system, I don't know what the fix is. But as it stands now, a lot of people using Etcher on Windows 11 get a flash failed error even when it is successful.

Cc: @builder555 who approved the original patch. Can't seem to tag the original patch author.

More details: Fails on the PCI flash on the motherboard, works on a USB-C reader. So the issue seems to be related to the flash hardware, possibly the unmount. The screensaver error is superfluous, as @aethernet noted. Will do some more tests.
