I was able to get rid of the error by turning off the Command Palette feature under the Dashboard. Apparently the Command Palette is a new feature with v0.90.0 and afterwards and therefore the error did not show up with the prior versions. BTW, there is a new v0.90.1 at the link in the OP. The error persists there as well unless of course the Command Palette feature is again turned off.
