It's been a known issue and it had been fixed for the next maintenance update v20.3 which will be release soon.

I'm running the ChartBrowser Sample(v20.2) and it hangs when selecting charts like Line Styles, Lines, Spline, etc. 
I checked and an infinite loop occurs in CXTPChartDiagram2DAxisView::CreateTickMarks.

An overflow occurs here and it is changed to a negative value, resulting in an infinite loop.

CXTPChartDiagram2DAxisView::CreateTickMarks(
...
while (dMark < dAxisMaxValue + CXTPMathUtils::m_dEPS)
{
...
   
// Here it is changed to a negative value.  
dMark *= m_MarkCorrectionCoef;
dMark = CXTPMathUtils::Round(dMark);    
dMark /= m_MarkCorrectionCoef;
In this case, the values were:
double dViewMaxValue is 40431.5999
m_MarkCorrectionCoef is 1000000
dMark is 2852.516352 => 2852516352 => -2147483648.0000000  => -2147.4836479999999
This value is repeated over and over again.


 And when changing the chart style, the following exception occurs.(multiple lines)

Exception thrown at 0x00007FFFFEFC4F69 (KernelBase.dll) in ChartBrowser.exe: 0xE0000001 (parameters: 0xFFFFFFFF80004005).
