Update 2:
A popup came from the system software updater and wanted to update. I updated and after that update, I have this issue
Update 3:
I didn't know which third-party app to remove, so I didn't remove any third-party apps.

If you really want to use the PPA
It seems that the package libpcre2-posix2 is trying to overwrite a library used by libpcre2-posix3.
Give apt the permission to overwrite the file.
sudo apt-get -o Dpkg::Options::="--force-overwrite" install libpcre2-posix2 Then, run sudo apt update, and sudo apt install -f and sudo apt upgrade.
If you don't want to use the PPA
The following command should remove the PPA and the conflicting packages.
sudo apt install ppa-purge sudo ppa-purge ppa:ondrej/php
