6 years ago Unable to open .yml files in STS 3.8.4. Recently upgraded STS to 3.9.4.RELEASE
How did you upgrade? The upgrade process using eclipse update site is quite messy and a bit unreliable.
It sounds like something has gone wrong and there are some plugins missing or having incompatible version inside the upgraded product. You can try restarting STS and adding the '-clean' option to STS.ini file. But this is a long shot and probably will not work.
The easiest is probably to just download a clean and 'fresh' copy of the STS 3.9.4 distribution build instead and use that. The distribution build contains exactly the version / collection of plugins we intended and isn't subject to Eclipse messy upgrade process not doing the right thing.
I realize that this may be a bit annoying for you if you have installed other add-ons yourself (you'll have to reinstall them in the new STS version), but its probably less annoying than dealing with a broken upgrade and trying to repair it.

Unable to open .yml files in STS 3.8.4. Recently upgraded STS to 3.9.4.RELEASE. Error Message: **An error has occurred. See error log for more details.
Plug-in "org.springframework.ide.eclipse.boot.properties.editor.yaml" was unable to instantiate class "org.springframework.ide.eclipse.boot.properties.editor.yaml.SpringYamlEditor". Could not initialize class org.yaml.snakeyaml.nodes.Tag**
I tried placing the new version of snakeyaml in plugins folder org.yaml.snakeyaml_1.15.0.jar but did not work.
This issue is happening after the upgrade.
Complete stacktrace:
