Switched from 2019 to 2020 and files open fine, but when I try to place a component I get "Serious Error - invalid stoul argument". Anyone else having this issue?
I've tried opening the part or assembly and saving before placing and still nothing. I also tried searching that error description and noting points back to inventor.
It would appear that this issue is being investigated. Doesn't help you in the here and now I know.
Are there some macro associated with this file you are trying to insert?

As for the macro, I don't believe so. I've never worked with anything using macros in inventor that I am aware of.
It did allow me to create a new assembly and place a component (same one that gave the error). So I guess the work around they suggested is good. Small inconvenience, but at least the components are usable still. I was worried that I would have to recreate all of my commonly used files.
I only asked about the macros because in researching this error, it seemed like it might have been linked to C++ or other macro type software.
I am glad for now the work around they suggested works for you. At least it is an out.

**UPDATE**
The "work around" is junk. It works for the first component added, but after that it has the same error and also after you save. Then if you try to insert that component into a new assembly it has the error as well. I am thinking about uninstalling and going back to 2019. Kind of dead in the water here. Don't want to draw everything again.
That doesn't make any sense why it would work for just the first component and not the balance.
Maybe one of the Autodesk guys can chime in like @johnsonshiue

Hi David,
Yes, absolutely, the defect will be fixed in the coming 2020.1 update. The error message should not appear in any existing file or newly placed file. I cannot comment when exactly the update will be released. But, it is soon.
Many thanks!
Hi Rudy,
I hope you don't mind I reply in English. This defect should have been fixed on the latest update to 2021 and 2020. What release of Inventor are you running?
Many thanks!
