Please help us isolate the issue with the following:

1. Your version of TypeScript
2. The content of your tsconfig.json file
3. Any @magic-ext/* packages you're using (and their versions)
4. A reproducible example

I haven't been able to reproduce this, so will need a bit more help from you to isolate the issue. Let me know if you can put together a reproduction.

[mwawrusch]

Repro is easy. Create angular app , upgrade to v12, then include magic somewhere.

I created a sample for you - https://www.dropbox.com/s/nxlx4k27x5aihp6/magic.zip?dl=0

[mwawrusch]

THere are a few more errors, those go away if you set "allowSyntheticDefaultImports": true, in the tsconfig.json, which still leaves the .semver bug, and probably the typings bug.
