CD-R
Not sure if I should post this here but how would I format a write-protected CD-R on windows 10 every method I tried failed?

If it's write protected, you can't erase it.
If you want a CD that can be re-used you would need some CD-RW.
Same with DVD for that matter. DVD-RW
How to Format a CDFS | It Still Works
The CD-R disc you are trying to format must be blank. If the CD is not blank, formatting will not be available. Do not abort the formatting process once it has begun. Aborting will only result in incompletion of the process. As a result, you will have to start over, and none of the formatting progress will be stored. Do not remove the disc, once it is formatted. Whatever action you desire to take for the disc should be conducted while it is in the computer. Otherwise, the formatting process will be null and void.The Compact Disc File System (CDFS) is the file formatting system used by optical disc media to designate a compact disc (CD). All CDs, whether audio, video or data, are all formatted in a type of CDFS. If you want to format that file system and remove the data on the disc, you can do so if the disc is a CD-ReWritable (CD-RW). CD-RWs are a special type of compact disc that allow you to write, erase, and rewrite content to them at will. You can format the contents of a CDFS on a CD-RW using Windows.

CD-RW and packet writing (what is used with an RW) are the least reliable. known to lose data and/or format. If you plan on using RW media, do not have your only copy of data on the RW. This used to be a hot issue on the Dell forums. Apparently most have abandoned this method (and CD's are becoming a thing of the past) as the problem reports about this have dried up.

To what purpose?
If you're doing it to erase the CD, I suggest shredding it instead. (My home shredder cheerfully eats CDs.)

If it has been written to {& finalised***} once already then it cannot be formatted or written to again. That's how CD-Rs are supposed to behave.
If it has never been written to then I suggest that either the disk or the disk writer is defective.
Do consider switching to external hard drives & memory sticks instead. They are reliable & versatile.

Most CD-Rs when writing is done are finalized so no more writing can be done on them.
However, with the proper software you can start by creating a Multiple session CD-R disc. When you are done writing you purposely don't finalize it. During later times you can write mores data sessions) to it. When are finally done adding data to it you then finalize the disc so no more data can be added to it. Let me emphasize you still cannot overwrite data on that type of disc. You can only add new data where none was written before.
