Coinjoin: "Pairing failed, retrying" anonymyizing process stuck

First time using coinjoin. I created coinjoin account, sent $300 worth of BTC. Went away for a few hours. Now, 2/3 of BTC is still in Anonymizing column, 1/3 is in Private column. Message “Pairing failed, retrying” constant. I closed desktop app (linux), but kept Trezor ModelT connected–This didn’t change behavior.

What should I do?

Selecting coins for the next round
Retrying pairing

keeps repeating this over and over for many hours without progress
I stropped, rescanned and restarted but it still appears to be stuck
How many hours should I give it before trying to stop it.

I have already paid a substantial fee which I would hate to lose

If I have to stop it should I just transfer all the btc out of the coinjoin wallet
