[Xamarin Profiler] Unable to profile - could not retrieve list of iOS simulators

Question

Hi everybody,
Trying to profile my application on Enterprise VS subscription and Xamarin Profiler on simulator and real device with no success.
The log file says:

XamarinProfiler.Core.ProfilerService Error: 0 : [2021-05-14 08:32:50.8775] could not retrieve list of iOS simulators: System.IO.FileNotFoundException: Could not find file "/var/folders/7b/cxl7l_51597drkxfm37_z5zh0000gn/T/7wnnf3jo.mlpd"

Have no idea why this file is not exist, also have no idea how to retrive this file.
Xamarin Profiles > File > Save as - is not active

The log file under the cut
