What issue do you have?
I've just upgraded Joplin to version 3.1.24 on two different computers, and on both, the first time the Joplin window is opened, I get a message that Better Code Blocks may no longer be compatible.with Joplin. Is this a real problem - i.e. has there been an API change in 3.1.24 that might produce this, or is this an erroneous message?
Joplin 3.1.x switched from CodeMirror v5 to v6. CodeMirror 6 has a different plugin API. Although Joplin provides a limited plugin compatibility layer, many plugins designed for CodeMirror 5 are incompatible. To continue using Better Code Blocks with Joplin v3.1.x, the legacy (CodeMirror 5) Markdown editor can be enabled in settings > general > advanced.
See this GitHub issue on the "Better Code Blocks" plugin's repository for details:
