The following steps have been tested on Kubuntu 20.04 with Oracle JDK 17. The original JRE (folder) shipped with CCS has been deleted.
Use standalone Nashron from OpenJDK. Create a folder named "nashorn" in the same folder with "ccstudio" and "eclipse", unzip the jars into the newly created folder. Edit "./ccs1110/ccs/eclipse/plugins/com.ti.dvt.control.engine_4.1.0.202105121547/META-INF/MANIFEST.MF", so that the final file looks like this:
Manifest-Version: 1.0

The only change is the Bundle-ClassPath: field.
Now CCS is ready to go. If it fails, try launch with ./ccstudio -clean and adding these lines to ccstudio.ini:
--add-modules=ALL-SYSTEM
-Dpolyglot.js.nashorn-compact=true
