Why can't I compile my React-native apps anymore?

Question

I'm gonna ask your guidance/help for a problem I've been encountering for several days now,

I can create a new react native project (via npx react-native init projectName), but when I try to run it, either with npx react-native run-ios or yarn ios, I get the following error message:

The following build commands failed: CompileC /Users/user/Library/Developer/Xcode/DerivedData/Trickster-ejsutjhruuvmqjedsaarumhaquan/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/RCT-Folly.build/Objects-normal/x86_64/SysUio.o /Users/user/Dev/Mobile/React
Native/Trickster/ios/Pods/RCT-Folly/folly/portability/SysUio.cpp normal x86_64 c++ com.apple.compilers.llvm.clang.1_0.compiler (in target 'RCT-Folly' from project 'Pods')

I've already cleaned yarn/npm cache, cleaned Xcode's DerivedData folder, even uninstalled node and react native from my computer, so I'm kinda lost tbh.

Here are my specs: MacBook Pro Mid 2014 with a 2.6GHz Core i5, 8Gbs of ram running macOS Monterey 12.2.1 npm version 8.5.2, 1.22.17 and Xcode 13.2.1.

Sorry in advance if I don't answer fast, I'm a bit ill atm so kinda occupying my time till I'm better

It seems the problem lies here /ios/Pods/RCT-Folly/folly/portability/Time.h, at this line: typedef uint8_t clockid_t; Xcode gives me the following error message: Typedef redefinition with different types ('uint8_t' (aka 'unsigned char') vs 'enum clockid_t')

This problem can be for several reasons. To avoid going into so much explanation If the application worked at some point

Delete the app in the device and
run yarn android or npm android or
delete the build folder and delete the app in the device and
run yarn android or npm android or
on Android delete and reinstall the device then
run yarn android or npm android

That's works for me
