Same version, same behaviour. Approx 30 second to start.

[smurphos]

In a terminal - nemo -q; NEMO_BENCHMARK_LOADING=1 nemo --debug Report the output. If that produces a quick launch, use your PC as normal for a while until you notice nemo loading slowing down and then run NEMO_BENCHMARK_LOADING=1 nemo --debug. Report the output.

To eliminate some sort of user configuration issue, can you make a new user account and try nemo there?
