Suggest the User start with Points 1 to 4 and then Test

Still having issues, move onto Steps 5 and 6 and Test Again

Still no resolve - move onto Step 7 and follow instructions therein 

1 - Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.

2 - Safe Mode will also eliminate Third Party Software, extensions and drivers from loading. It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance 

3 - Does the issue present in this mode ?

4 - Sometimes a Safe Boot followed by a Normal Boot will just put things right.

5 - If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.

6 - If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.

7 - Download the Application Etrecheck directly from the Developer.

Q - Problem: Other problem

Q - Description: Silhouette Studio takes approximately 20 minutes to startup

Q -  kernel panics - This system has experienced kernel panics. This could be a sign of hardware failure.

A - If in doubt >>

1 - Have the computer evaluated by the Professionals who have the Special Hardware Software and Expertise to diagnose the issue and offer possible solutions

2 - Make an Appointment at the Apple Genius Bar and have them evaluate the computer

A - This dovetails into below " User Launch Agents and User Login Items "

Hardware Information:

  MacBook Pro (16-inch, 2019)

Q - Drives:

Q - disk0 - APPLE SSD AP0512N 500.28 GB (Solid State - TRIM: Yes) 

  disk1s1s1 - Macintosh HD [APFS Snapshot]

  Size: 499.96 GB

 A - It is generally a good computer practice to alway keep at least 15% to 20% of the Total Drive Capacity’s as Empty Space. 

Allowing the computer to drop below these guidelines may eventually, cause unintended consequences.

There is Purgeable Space and there is Empty Space.

Purgeable Space which is Controlled by the Operating System. When the Operating Systems decides the computer needs additional Empty Space, it will move a portion of the Purgeable to Empty space

AFAIK - there is no User Actions to hasten this transition from Purgeable to Empty Space

It can day or longer before this will occur

A - The combination of User Launch Agents and User Login Items is going to have a major impact of Opening any additional Applications 

A - Suggest to selectively choose those Application that are really required to start when the Computer First Boots up and Remove that are Not

You may have already experience the Benefit of not having all these Appliation Launching at Start when you make the Other User Account. The Slow loading Application sprung to life  like it should do.

Thank you for the report

Will have a look and get back to you shortly
