Hey @parvezghumra
Yes i totally understand that. I was struggling to find a fix for the missing dependencies as I was unable to add them, and I saw someone recommend editing the file in another post.
When i try to import the file I get this:

I have tried to Add Existing to the solution but when I search for it, nothing comes up:

I think these came from a Power Portal that i created in the past on the DEV environment but then deleted as it didn't get used. I'm unable to create a power portal in any environment now as IT has cracked down on creation permissions.
Any ideas on how to get around this? I'm really struggling and have been trying everything including downloading the solution, unzipping the file and adding files matching the file name into the webresources folder and re-zipping.
I've created a new solution and exported, imported, then added the missing dependencies that was being flagged (same in the 1st screenshot). then exported and imported again, but the same missing dependencies are flagged. Then when i go to add the web resources, they are in the initial solution.
