Can't access management app, can't use Shizuku when SUI installed

[e-t-l]

After flashing the latest version of the Zygisk-Sui module in Magisk (Kitsune fork), no part of it works. I don't get any option to access the management app when op ening Dev settings or under Settings app shortcuts, and entering the dialing code just shows an error that it's not a valid code.

Additionally, when the Sui module is active, apps cannot access Shizuku. Shizuku still runs as expected, but apps that have Shizuku permission granted will behave as if Shizuku is not installed/running. Disabling Sui fixes this.

Please advise.

I tried to get the management app by running pm install /data/adb/modules/zygisk-sui/sui.apk
but it returns the error:
Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES: Failed to collect certificates from /data/app/vmdl1762216583.tmp/base.apk: Attempt to get length of null array].

Did you not sign the apk?
