@Matthias Nagel (and interested parties): This worked for me:
#### rebuild php-apcu.so
mkdir apcu
cd apcu
git clone -b ubuntu/mantic https://git.launchpad.net/ubuntu/+source/php-apcu
ls -l
cd php-apcu/apcu-5.1.22
phpize
./configure --enable-apcu
make
make test
### as root
cp modules/apcu.so /usr/lib/php/20220829/
php -version
