Verify error: directory missing

Arduino: 1.8.15; all libraries and boards up to date
Board: Mkr Wifi 1010
Computer: MacBook Pro (M1, 2020)
MacOS: Big Sur 11.2.3

When I try to verify my sketch I get the following error:

fork/exec /Users/gary/Library/Arduino15/packages/arduino/tools/arm-none-eabi-gcc/7-2017q4/bin/arm-none-eabi-g++: no such file or directory
Error compiling for board Arduino MKR WiFi 1010.

Looking at this path, I find that the path breaks down at the directory 7-2017q4. There is no bin directory in 7-2027q4.
I have updated everything to the latest versions, but to no avail. Any suggestions?

Hi @garywil. Please try the fix described in this Arduino Help Center article:

Let me know if you have any questions or problems.

Thanks! Deleting Packages and reinstalling the board fixed the problem!

You're welcome. I'm glad to hear it's working now. Enjoy!
