ClientApp/node_modules/rxjs/index.d.ts not found

Question

I am trying to get my Angular 13 app working. I have basically a blank project, but can't get the dependency versioning right. I have found another question similar to this on Stack Overflow, but the answer was to upgrade my Typescript version, which I have done. I will list my dependencies from my package.json file below. If I use rxjs version 7, it gives me the error:

Error TS6053 File 'C:/Users/myname/Source/Repos/KESSDI/KESSDI/ClientApp/node_modules/rxjs/index.d.ts' not found. The file is in the program because: Root file specified for compilation

The error does not seem to cause any problems. It compiles and seems to run fine, but I do not wish to start this project with an ominous error message. If I use rxjs version 6, it does not give me the error, but another one of my dependencies requires version 7 to run. I am using Visual Studio 2022. Below is the list of dependencies:
