Hi,

Working with Quartus Pro 25.1, we are having the following error when trying to compile:

invalid command name "End-trace"

while executing

"unknown_original End-trace"

("eval" body line 1)

invoked from within

"eval unknown_original $cmd $args"

(procedure "::unknown" line 7)

invoked from within

"End-trace"

invoked from within

"flng::run_flow_command -flow "compile""

It hapened suddenly in projects that were compiling flawesly before, we have reproduce this error is different machines. 

Could you please help us to solve this?
