I have some PID blocks created in R2016B, I have converted the model to R2019B. The Model runs fine but I cannot delete some PID blocks. I get a message about error trying to execute the 'DeleteFcn' and specific reference to Callback string is 'pid pack.PID Config.closeTuner(gcbh)'
These were PID blocks which I had modified (which I think means I had to unlink them or something but I cannot recall). Even if I delete all the content inside the subsystem I still cannot delete it.
I verified I still do indeed have an active license for Simulink Control Design.

It looks like the DeleteFcn in 2016 was pidpack.PIDConfig.closeTuner(gcbh) while in 2019 it is pidpack.PIDConfig.utilcloseTuner(gcbh). Try this:
set_param(gcbh, 'DeleteFcn', 'pidpack.PIDConfig.utilcloseTuner(gcbh)')
3. Try to delete the block
If this still doesn't work, I would try just deleting the callback altogether:
set_param(gcbh, 'DeleteFcn', '')
