Ok, I have a possible workaround. This short screen recording demonstrates the solution. It works in Studio and Assistant and also works in and out of PIP.
- Although this is acceptable, it questions the Start Process activity if more applications do not work in PIP mode when opened using Start Process
- Besides, starting an application with Win + r means adding 3 steps to the process as opposed to just one when using the Start Process activity
