Welp.
Installed the apk onto nox emulator and it works well.
I think the issue is with Android 11, which made some changes in the file system, for example the usual app folders under Android/data is empty(likely hidden from user), as I am unable to see any folders when attempting to copy ecd file. :(
Author might have to check for the mod compatibility with the latest android for future releases.
Only odd thing is Android 11 was working well with the previous version 2.11.0 modded apk
