There is an alternative project similar to pandomium by @FriwiDev, but with a much newer version of JCEF here:
https://github.com/jcefmaven/jcefmaven

Currently, newer JCEF releases cause blank pages and page loading errors on pandomium.
They also only support (compared to older releases) fewer operating systems.
That's why we will stay on the current JCEF version until an actual working JCEF version is released.
If you want to try out the old broken Pandomium release with a newer JCEF version yourself here you go:
https://github.com/dzikoysk/pandomium/releases/tag/1.1.1-JCEF-v1.0.10-92.0.25%2Bgd15cfa8%2Bchromium-92.0.4515.131
