Unity startup: 5 minutes 40 seconds

Unity Engine
1

Hello

I’ve been wondering for a while now why the startup takes that long (2019.4.18f1). From clicking Unity Hub to an open project it took 5:40min, where it got stuck for minutes showing only “Importing” without refreshing the loading bar. It’s not that my project would be huge. The loading time got worse and worse with each Unity version that I upgraded to. Same goes for the compilation times. I found this sticky thread but I don’t know whether that has anything to do with it.

Can anyone help?

any info inside the editor.log file?

hmmm, this might lead to something, but how to get further from there?

Need to check that out after a computer restart. I still had to select my project in Untiy hub (I did enter the project location though) but from the second start on, it starts way faster. So I cannot reproduce after the first start. How can I tell whether the profiler actually started? Will it give me additional info on exactly the lines I posted?

well, I don’t see any additional information concerning the out-of-date-assets in the log file.

how do I get additional information on which package is causing this?
