TWRP Custom Recovery, Failed to mount /cust

[Sk Safowan]

When I try to wipe anything or flash a new rom in Latest TWRP, It is Showing "failed to mount cust, no such file or directory"

And the cust partition isn't mounting in the TWRP Mount Folder

I searched everywhere on internet, I couldn't find anything related to "failed to mount cust"

Please Let me any possible solution if you know. I am using Poco F1
