Hi Ester Munk,  

 

Thanks for your update.  

 

We have checked your attachment and your provided user control files are not enough to understand your use case scenario and to replicate this issue since it requires more dependent file to make it runnable. Hence, we have prepared a simple sample with chart related code snippet and tested the reported crash issue, but we were unable to replicate it on our end.  

 

Please find the tested sample

We can fix the reported issue based on the stack trace but without knowing the proper replicating steps, fixing the issue may fail with any other scenarios.
