DateTime parse problems after update version

[EtaLasquera]

Hi guys... we upgrade from 5.16 and 5.29 to 5.47.
All our projects with datetime.parse functions became to error, the problem is culture info....
Our system date time format:
dd/MM/yyyy

Old projects:

DateTime dt = DateTime.Parse("01/12/2020");
project.SendInfoToLog("D: "+dt.Day.ToString());
project.SendInfoToLog("M: "+dt.Month.ToString());
project.SendInfoToLog("Y: "+dt.Year.ToString());

Result:
D: 01
M: 12
Y: 2020

With new verions:
D:12
M: 01
Y: 2020

Edit.:
5.44 >> working
5.45. >> working
5.46 >> Broken
5.47 >> Broken

Solved, move to bugs.

Not sure what is actually the bug there. DateTime format depends on regional and language settings in your system.
For some countries it can be Month/Day/Year, for others Day/Month/Year

For a strange reason on the same operational system and same computer, versions 5.45 and earlier the result of a date time parse works fine and 5.46 and newer not work.

If not a bug, this is a bad implementation: overide system language settings and use only one.
