So long as you can see the folders correctly, clear the caches without errors, and delete the package_cache folder, it should be OK. Beyond that, I am not sure what is causing these issues. If they are still causing you problems, you could go back to last week's ROM.
Last time it worked fine 20.11.5_v12-11, should I flash with TWRP - 3.4.2b-0623 ?
