On upgrading Burst package from 1.4.1 to 1.4.2, InvalidOperationExceptions are thrown. Refer the attached video

Steps to reproduce:
1) Create a new project
2) Window > Package Manager > Install Burst 1.4.1
3) Upgrade Burst to 1.4.2

Actual result: InvalidOperationException is thrown in console

Expected result: No errors should be thrown in console

Occurring in: 2021.1.0a8, 2020.2.0b14, 2020.1.9f1, 2019.412f1 when Package version is upgraded to 1.4.2

Working fine in: 2020.2.0b14, 2020.1.9f1, 2019.412f1 when Package version is upgraded to 1.4.1

Note: For 2021.1 only 1.4.2 package version is available. Bug can be reproduced by installing Animation rigging first and then upgrading Burst to 1.4.2 as a dependency
