Trim and Extend not working like it did in 2021 version.

Hi, I'm having a problem with trim and extend not working like it did in 2021 version. I used to be able to use both commands by selecting the command then the boundary line, then right click and green box what entities would Trim/Extend to that boundary line. now it just says error. I can select line by line but this takes time and also use power trim but only to the next line. can you please advise?
