Hi,
Sorry that you are seeing this issue.
Is this a new installation of Eclipse 2021-06 or a working copy of Eclipse + CodeMix that stopped working post updating to Eclipse 2021-06 from within the IDE?
Please note that CodeMix/AngularIDE have reached end of life and there will be no new releases. The alternative is MyEclipse 2021 which provides what CodeMix did and much more. Please refer to this doc for more details about CodeMix EOL and the tech supported by MyEclipse : https://www.genuitec.com/products/codemix/end-of-life-notice/
MyEclipse offers a 30 day trial period. You can evaluate the product and buy it if it fits your requirements. The installer is available here.
Please let us know if you have any further questions.
