Packaging and compile error: import failed for PositioningAlgorithm

Project cannot packaging. Usially i’m compile project once in mounth or less and this error manifested for the first time. I didn’t do anything significant in the project and I can’t even suggest the causes of the problem.
I attach two log files and error code in output log.

(I tryed it find solve of my problem and now shaders need to be recompile. Logs was a cleared, but problem is’nt solved. Logs will be attached as soon as I can. Thank you.)

Problem is solved.
She was called by plagin “Graph Formatter”. Plagin is just remove tables in blueprints and I could not imagine what it can be a problem.
The solution to this problem is to remove the plugin “Graph Formatter”. Its all what we needed.
