.jar file do not open with terminal

Hey,

I want to open a .jar file with the terminal 'java -jar filename.jar' and it does not work. The terminal suppose me the error: Unable to access jarfile filename.jar

All times before, there was no problem to start normally with double click but a new update destroyed it.

I'm locking for the made mistake while create the update for changing it.

Please help me !😟
