Nx migrate error moving from nx@21.1.0 to nx@latest: Cannot find module '@angular/core'

[rpd10]

Current Behavior

Attempting a Nx migration from version 21.1.3 to 21.2.0 yields errors on any migration from @angular/core. I found #31838 and attempted the workarounds there, to no avail. I've tried both the Nx Console migrate UI, and the CLI. I've been able to narrow it down to the update from 21.1 => 21.2. The logs below

• When running via the CLI, the migration appears to hang on the inject-flags migration
• When running via the migrate UI, I get the following error for any Angular related migration, starting with inject-flags:

Cannot find module '@angular/core'

- /Users/rydiehl/.vscode/extensions/nrwl.angular-console-18.67.0/main.js
- /Applications/Visual Studio Code.app/Contents/Resources/app/out/vs/workbench/api/node/extensionHostProcess.js

If I skip the migration, it happens for any other Angular-related migration.

Expected Behavior

Migration works without errors and applies all relevant Angular migrations without forcing me to skip them
