Hi!
We are trying to upgrade to the new version of the library 6.45.1 and are trying to compile the project. We get several errors in the library itself. Please tell me what could be the reasons for such errors.

Hi
There is one bug left in version 4.6.1

if you add “physicsBody” to “babylonjs/Physics/v2”, then the project compiles successfully

~~that was fixed in a recent PR, but let me check again. Are you sure the version you are referencing is correct? or do you mean 6.46.1?~~
Sorry about that - I will release a patch very soon.
