Samsung S21 shows offline on ADB after carrier update, or play services update

Question

My company issued Samsung S21 was working properly with android studio up until Monday Oct 25th when T-Mobile forced a monthly carrier update. The update happened on Monday night. Tuesday morning Android Studio can no longer see the device via usb ADB.

Here's what Android studio shows:

Here are the "default usb modes" I have on this phone:

adb devices shows this:

adb devices
List of devices attached
R5CNC0EZMDR     offline

adb devices -l shows this:

adb devices -l
List of devices attached
R5CNC0EZMDR            offline usb:4395008X transport_id:265

things I’ve tried:

• tried every single usb configuration
• reset usb debugging on the phone
• revoked usb debug authorizations
• changed cable
• changed usb port (side of the computer)
• adb kill server, adb start server
• reset the phone to factory settings
• enabled usb debug
• disabled usb debug / enabled usb debug again

For what it's worth, I'm using a Mac running Big Sur 11.5.2, with Android Studio Artic Fox patch 3. The phone is a US version Samsung S21 connected via usb-C cable to the computer directly, along with 2 different adapters I've tried.

Also, a different phone (Samsung S20) works fine with the same computer setup.

Any suggestions on what I can do to fix this and get ADB to connect to the phone again?

Thank you!
