It looks like blazemeter.jmeter.http2 code issue to me.

The code is invasive, and it searches for a JCheckBox: https://github.com/Blazemeter/jmeter-http2-plugin/blob/94060bdf2f4f04157e6cb1cee408ac44cde1b31b/src/main/java/com/blazemeter/jmeter/http2/sampler/gui/HTTP2SamplerPanel.java#L58-L72

Apparently, the checkbox is no longer there since it has been replaced with an editable "checkbox with the expression". The code relies on internal structures, and it does not handle nulls properly, so I don't quite like to spend my time adjusting JMeter to make the exact code in http2 work, and I do not like to block the 5.6 release either. Surely they can fix the NPE and release an update.
