WatchOS 7.3.1 update fixes charging error for Apple Watch Series 5 and SE

Apple Watch Series 5 and SE users recently encountered a nasty bug that couldn't charge their device after turning on the Power Reserve feature. This is a feature that you can turn on when the battery life on your device drops to 10%. If the battery life gets any lower, Power Reserve will turn on automatically. You can also turn it on manually, and press the side button until the Apple logo appears. When Power Reserve is turned on, the watch will only show the time.

Apple just released watchOS version 7.3.1 to fix this error. To install, users access General Settings => Software Update. To install new software, your Apple Watch needs to have at least 50% battery, needs to be placed on the charger, and it must be within range of the iPhone.
