I'm beginning to suspect that W10 1803 and W8.1 are going to be those hardest hit by Sigil 0.9.11+ performance issues. I'm not sure anything other than 1809 has received the partial "fixes" for the delays that were introduced by Control Flow Guard.
Another thing to try is to disable CFG for the Sigil binary. I can't vouch for Windows 8.1 but I know that Windows 10 (1803 and 1809) can override the system-wide security settings on a program by program basis. In fact, Windows has already overridden individual security settings for several binaries.
From Windows Security, click on App & browser Control; scroll down to Exploit protection and click the "Exploit protection settings" link. There's System overrides (that I do not recommend changing unless you're sure of what you're doing), and there's Program overrides. You can add Sigil.exe (by name or by explicit path) and then edit the individual overrides you want to affect Sigil. Control Flow Guard is on by default and you can override that and turn it off for Sigil only.
You can easily reverse that override, or remove Sigil entirely from the program list once done testing.
