Outside of that;
The following are thoughts that come to my mind in your situation, as I have not experienced this. Please don’t be offended if the suggestions seem rudimentary as I am not assuming a level of knowledge just offering my thoughts.
Were you able to re-add them to the Wyze App?
What does the battery status show? I have been known to plug in unplugged things before? Funny but true.
Did you disconnect the buds from the original host device before trying to re-add just for good measure.
Are the buds connected to another device not allowing them to connect to the device of choice. Today these are 1 to 1 only. If they are connected to another device try removing them from the other device. There are wish list items out there requesting that these buds be able to connect to multiple devices
