[linux] debugging with gdb not working anymore

os: ubuntu 20.04
vscode: 1.48.2
cpptools: v0.29.0 (tried both default & insiders channels)
gdb: 9.1

Hi,

i'm trying to launch the debugger
it was working fine a month ago (before vacation)
now I get an error. The program doesn't seem to start at all, like nothing gets executed.
however i can debug it manually using gdb --args myprogram myargs

Terminal :

&"warning: GDB: Failed to set controlling terminal: Operation not permitted\n"
/bin/bash: -c: line 0: unexpected EOF while looking for matching `}'
/bin/bash: -c: line 1: syntax error: unexpected end of file
[1] + Done                       "/usr/bin/gdb" --interpreter=mi --tty=${DbgTerm} 0<"/tmp/Microsoft-MIEngine-In-op229nom.ijv" 1>"/tmp/Microsoft-MIEngine-Out-cwku9ms3.0ks"

Debug Console :

1: (959) <-1017-exec-run
1: (960) ->=thread-group-started,id="i1",pid="723395"
1: (960) ->=thread-created,id="1",group-id="i1"
1: (961) ->=thread-exited,id="1",group-id="i1"
1: (961) ->=thread-group-exited,id="i1"
1: (961) ->1017^error,msg="During startup program exited with code 1."
1: (961) ->(gdb)
1: (966) <-1018-thread-info 1
1: (966) ->1018^done,threads=[]

The issue names no repository files, tests, or entry points. Start by reproducing the VS Code debugger launch with Ubuntu 20.04, GDB 9.1, and the listed extension version, then compare the terminal and Debug Console output. Done means the program launches under the debugger without the shell syntax error.
