I'm experiencing (almost!) the very same error, but my device is a Android 12 tablet, BLU M10L Plus.

Apparently some applications fail to create its own data directory under /storage/emulated/0/Android/data on this tablet for no reason at all, causing weird crashes or failures like this one, and yes, this means Shizuku is unusable on this device. But unlike the OP, I get a ENOENT because the directory doesn't exist:

java.io.FileNotFoundException: /storage/emulated/0/Android/data/moe.shizuku.privileged.api/starter: open failed: ENOENT (No such file or directory)

FWIW, I'm using also a 128GB MicroSD card as application storage, but moving apps between SD and internal storage make no difference. Manually creating the moe.shizuku.privileged.api folder using the internal Files app turns the error into a EACCESS, as expected (since the directory is not owned by the app). I don't have a clue on what could be failing on this tablet, since some apps CAN create their own data subdirectories! Short of trying a factory reset or getting rid of the SD card for app storage (which I do not want to do as this tablet only has 32GB of internal flash), I'm running out of ideas here.
