Designer goes blank/white after code change with error in code

Hi Guys

Using visual studio 2019 and C# forms.

I am quite new to Syncfusion, but since I have been using sync fusion controls I have been experienceing the below

Have my mainform open in designer and go to code to make changes in the mainform.cs
If I have an error in the code and I navigate back to the designer tab, the designer is blank/white, I then close the tab and re open my mainform and its fine again..

Any of you experiencing this and might know a solution?

I am uninstalling everything now as my last resort. Could not find any threads containing similar issue.

Same issue here. Design page is getting totally blank by debugging. I have to close and reopen the page everytime i want to edit it. Just added an empty checkbox, combobox and numericUpDown. Don't have any errors.

PS: I had it also with errors like OP, can't remember exactly how, there are also many other not expected behaviours when editing the controls.
