Thanks for reporting. We'll fix this problem in our next release.

@csabella, this one is yours :-) I think it happens when the kernel takes too much time to start.

This is the old code before my change in #6699, but we don't know what version of Spyder the OP is running. @ccordoba12 , do you think one of the other fixes to the console would have helped with the kernel start up time? Just thinking if @angelalarc99 updates to 3.2.8, then it may resolve their issue.

I will, however, also put in a check to make sure self.t0 isn't None. :-)

I made several changes to improve kernel startup time in the same release the timing functionality was introduced. After that, nothing significant has changed in that regard.

I will, however, also put in a check to make sure self.t0 isn't None. :-)

Thanks a lot for your quick response!
