3.8.16

Rollback to Electron v21.3.3 because v22.0.0 created compatibility issues.

As stated on Electron's Releases page, Electron package is sunsetting Windows 7/8/8.1
"Electron will be ending support for Windows 7/8/8.1 after version 22.x.y following Chromium's plan to end support. Older versions of Electron will continue to work, but no further updates will be made for these operating systems."

We will maintain the Electron version in v21 until the v22 gets stable enough.
