[Request] Please support newer electron.

[sukanka]

Note: This is a custom-rebuilt version with electron25, as electron19 has been dropped in archlinux official repo, I tried to rebuild etcher with newer electron (namely electron 22 to 25).
All builds succeded but failed to flash any image.

---

update: with 1.18.13 I still cannot flash any image. When I select an image, it pops

And I see the logs in console says

But etcher built with electron19 works fine.

My build script: github gist

• Etcher version: 1.18.11
• Operating system and architecture: Archlinux x86_64
• Image flashed: archlinux-2023.07.01-x86_64.iso (or any other)
• What do you think should have happened: flashed successfully.
• What happened:
  Failed to flash (any) image.

After the password is entered, the following error occurs.

• Do you see any meaningful error information in the DevTools?

We know it can't run on electron 20 and up due to security related changes in electron and chromium. This is a good thing as it makes it harder for random dev to shoot themself in the foot.
But it broke legitimate use case as ours.
We're currently working to work around the new limitations.
