Wrong or pending file size (32 bit system) NC20

Files sizes of files bigger than ~4GB are not saved and displayed correctly.

I looked up the oc_filecache in the database and there are the file sizes also not correct.

Maybe it has to do with my 32bit system (Raspberry Pi 4), because integers in php are only 4byte.
So it can just save 2^32 = 4.294.967.296 different states, which means file sizes (as unsigned ints) up to 4,29 GB.

Does anyone have a idea how it can be fixed?

My Specs:
NC 20.0.2
PHP 7.3.19
nginx 1.14.2
MariaDB 10.3.25
