As a UMC elder, and a conservative one, my advice to you will probably seem mixed.
First, the UMC will remain a viable church until the Lord removes its candlestick. That would indicate to me that that church no longer is a light where others can find salvation in Spirit and Truth. That is a "denominational" answer.
As far as YOUR local UMC, there are some of them quite far down the road of darkness and where there is little to zero hope that they will be a lighthouse for the lost. I would counsel leaving that church and finding one (whether Methodist or not) where salvation can be found.
If your church is one that still sheds the Light of the Lord's Truth, then I would counsel you to stay and fight the good fight along with the remainder of us who resist.

Thank you. My church is still worth fighting for. I feel that I was called to be a UM and I can’t walk away until I know that there’s nothing left but a building. I’m developing contacts among the conservatives in the UMC to remind me that we may be insurgents within our own church, but we are still fighting.
On Jan 1, I become chairman of our Church Council, so I am so encouraged to know that the people of the congregation chose me to lead them.
