Hi Slayer420L17,
You're conflating the amount of internal storage available on your iPhone (64 GB) with the amount of storage available for data and backups via your iCloud account (200 GB).
Your iPhone's storage capacity is nearly full - this is likely why it cannot process its content categories in the iPhone Storage view. There is no available space to write to the internal storage.
First, you should immediately perform a complete backup of your phone.

Next, you'll need to free up storage on your phone.
Use recommendations to optimize storage
In the Storage section of Settings, your device might offer recommendations for optimizing your storage. Tap Show All to see all the recommendations for your device.
Read the description of each recommendation, then tap Enable to turn it on or tap the recommendation to review the contents you can delete.

Your iCloud account's storage capacity is not an extension of your internal storage. It can be used to store copies of the data on your devices in the cloud.
