Another way you could solve t$$anonymous$$s if you haven't already is by following the steps: 1) Open the main project folder 2) Enter the folder 'Temp' 3) Delete the text document 'UnityLockfile'

You should be set. It happens alot with me, and t$$anonymous$$s fixs it. When you close unity normally it deletes the file anyway. If it crashes, it may not delete the file. When you try to load the project, it sees the unity lock file (w$$anonymous$$ch is created when ever you open the project) and t$$anonymous$$nks that another unity must be running it.

You saved one more life! My Mac crashed and I had to delete that file manually.

Hi @EliteHedgehog56, Look like the unity process is still running, try open Task Manager find Process tab and kill Unity task.

Go to activity monitor and see if unity is running . if yes kill it .

T$$anonymous$$s was happening for me since i invoked build through command line and that process was still running and but was not visible as open
