I was trying to run the ionic serve command but I keep getting the error

[ng] Error: The Angular Compiler requires TypeScript >=4.4.2 and <4.5.0 but 4.5.2 was found instead.

When I tried downgrading the typescript using this command

npm install typescript@">=4.4.2 <4.5.0" --save-dev --save-exact

And Also running the npm i ; The ionic serve command gets stuck at the generating browser application bundle phase setup.

When I checked my angular version I got the following:

enter image description here

Angular CLI: 13.0.4
Node: 16.10.0

Try this:

• replace typescript 4.5.2 with typescript 4.4.4

• run npm i again

I had the same problem. This answer helped me. But it refers to a maximum of version 12 Angular. For version 13 Angular, I used this in the project:
