Hi paes20705,
我和你有一樣的狀況, 經過奮鬥了一天後, 我在國外論壇找到相同狀況, 且其解法對我有效
伴隨狀況會是: 設定 乙太網路內容>共用>網際網路連線共用>允許其他網路使用者透過這台電腦的網際網路連線來連線 時, 會跳出"目前是ethernet_32772, 已改為乙太網路"類似的內容
主要原因在於把windows defender這個windows預設防火牆關掉了(disable state)
上面連結中, Gokul T提到
Based on my online research, the issue seems to occur on computers that have Windows Firewall disabled. Windows Firewall service has to be running even if you’re using another antivirus cum firewall program on your computer.
I’d recommend you to check for the status of the “Windows Firewall” service and set it to “Automatic”.
Follow these steps:
a. Click “Start”.
b. Type “services.msc” in the Start search box and hit “Enter”.
c. Right-click “Windows Firewall” and click “Properties”.
d. In the “General” tab, select “Automatic” under the “Startup type”.
e. Click "Start" to start the service.
f. Click “Apply” and “OK”.
Restart the computer and check if the issue gets fixed.

解法翻譯成中文就是, 必須要這狀況下, 先把windows defender啟用, 重開機後, 網路分享(ICS)/wifi熱點就會正常,
我這邊嘗試, 正常後把windows defender關掉並不會在正常狀況下再次影響網路分享(未來windows更新可能不保證, 呵呵)
