Ignition Designer Launcher - Error launching application: NoSuchFileException

This is sounding a bit like an issue myself and some others had with an Ignition upgrade: https://forum.inductiveautomation.com/t/8-1-35-upgrade-unable-to-extract-ignition-runtime-files-classes-jsa I think it started with the 8.1.33 bump of the Java Runtime to version 17. I suspect that the same issue that affected our upgrade is also affecting the clients. What I think happens is that when a client is run it fetches the resources from the gateway and extracts them - and like with the upgrade …

I replied as there as well, but this doesn't sound like a bug, it sounds like a problem with AV/security software.
