PS5 FW4.50 can't  installs game。

I created exfat using mkexfat.sh on ubantu, and after creating it, I used ubantu to load it to ensure that the file is complete and error free. However, when transferring to/mnt/ext/etaHEN/games and opening 1.5beta6, the scanning prompt shows an error in param.json. View the/data/imgmnt/PPSAXXXXX/sce_Sys/param.json file, all contents are blank. Usage failed。FW4.50 etaHEN2.5B kstuff1.67。
