Hi @Stanlay19 Thanks for your feedback.

Which web browser do you use? could you try this on console: "new Date(new Date().toLocaleString()+ " UTC").toISOString()" which got this error, but I can not reproduce it.

There is a fix about this issue, #4108.
Have a try with source code or wait for next release.

I have the same issue on win10 with python 3.9. In the first day it worked but in the second day I got Failed to create log dir: RangeError: Invalid time value. Tried the 4108 but does not help, I still have the same issue.

Version 2.4 does not work. Tried 2.3 and it is working so far.

@acured - may we add this to 2.5 test? just make sure that there are no regressions from 2.3 to 2.4 (then 2.5), thanks.

Fixed in v2.5.
