Syncing iPhone 11 Pro Max or iPad Pro 12.9 2020 to new MacBook Air M1 kills 3rd Party apps on those Devices.

Tl:dr at bottom.

Initial Issue

When I sync my iPhone 11 Pro Max (running Latest 14.3 iOS) and my iPad Pro 12.9 2020 (running latest 14.3 iPadOS) to my 4-day old MacBook Air M1(Running Latest version of MacOS Big SUR) it essentially kills 3rd Party apps on my devices other than the MacBook Air. I can try and open a 3rd Party app and unless already opened prior to Sync and still open in background it will start to open for a second and then return to home screen as if nothing happened.

Troubleshooting

I originally thought it was a issue with my iPhone and I troubleshooted as such. While I am a IT Admin I am no Apple Genius and am new to the Ecosystem after having avoided it my whole life until this year. Now I am in deep. I do, however, have good troubleshooting and googling/forum searching skills. I did the following to troubleshoot what I believed at the time was an iPhone issue;

1. Power on and Off Multiple times throughout all other Troubleshooting Steps.
2. Delete and reinstall the apps (Even though it was all 3rd Party Apps)
   1. This didn’t work either. The App deleted fine but when I tried to reinstall It would download ¾’s of the way and then go right back to as if I never clicked download.
3. Reset All Settings.
4. Restored from an iCloud Backup by Resetting Phone Completely and used my Backup to Setup Phone.

Submission was too long with all the troubleshooting steps I have taken and my Appointment with Apple Repair Specialist. So all that was put into the Additional Text, for anyone wanting to really get an Idea of what's going on I would suggest reading it.

Please Help

Hoping for some suggestions as searching for hours online has brought me no results and I can't find a single case of this otherwise. I have verified it is a genuine MacBook Air via its Serial number and can't think of anything else to try. This is my very first time with a Mac at all and feel out of my element. Any help, tips, guidance, or anything is appreciated.

When plugging iPhone or iPad into MacBook air and Syncing in Finder App it keeps me from opening third party apps. All major troubleshooting steps taken and still it's happening. Thought it was phone at first now closed in on MacBook and resetting it. Hoping for some help.
