I recently ported a project to PLCNext version 2025.6. After I deleted some function blocks, I got a few errors since the function blocks were referenced in the code. I started deleting the lines to clear the errors but after the last error was cleared, PLCNext Engineer crashed.
I tried creating errors in different parts of the project, but as soon as all the errors are cleared, the program crashes.
I am using global function blocks that are being accessed in different programs, so it could be related to that.
I attached the zip file containing the project, if anyone wants to check if the same happens on their system when clearing the syntax error in the project. This should give a good indication if the problem is related to my PC or the project.

Turns out it was a recursive dependency which caused the problem.
