Object detection error

Hi,
We are converting our app from Delphi 10.3.1 to Delphi 12.2

When we manually run applications, they are working fine. One form in one application crashes while it's run under TC 15.69.137.7 64bit (app it self it's 32-bit)

I then started to debug it with testcomplete and noticed that object spy also crashes it.

This is Eurekalogs bugreport (I translated 2.6 Message to English from Finnish)

  2.3 Module Name   : tcDbgAgent.dll
  2.4 Module Version: 15.69.139.7
  2.5 Type          : EStackOverflow
  2.6 Message       : Recursion is too deep. Stack overflow

                      Address:_(000676CC){tcDbgAgent.dll} [590B76CC] tcDbgAgent.DllCanUnloadNow + $554C.

Call stack is attached. Same form is working fine in d10.3.1compiled app 

What's wrong?
