You may have updated your Linux operating system to the new LTS: This may break the integrated web browser in Axon Ivy Designer. Since this is dependent on the Eclipse-Platform, we cannot update the Eclipse-Platform on the LTS 8 or 10 train, because we cannot guarantee for good quality and stability. On MAC the integrated web browser sometimes behaves a little a bit awkward.
At the moment there is one solution for LTS 8 and LTS 10. You can install via Eclipse Marketplace a third-party web browser. It will show an ugly watermark on the bottom but works smooth.
For the next LTS 12, we have updated the Eclipse Platform to the latest version and at least on Linux the web browser does not crash anymore.
