Errors after upgrading Angular

I recently had to update node to v14 for another project and it broke my nebular projects. I decided to go ahead and update Angular as well and as many packages as I could to get them working again, but am still running into errors. Currently I am running:
Angular CLI: 10.1.6
Node: 14.13.0
OS: win32 x64

Angular: 11.0.0-next.5
... animations, common, compiler, compiler-cli, core, forms
... language-service, platform-browser, platform-browser-dynamic
... router
Ivy Workspace: Yes

@angular/cli 10.1.6

Here are the errors:
