Troubleshooting audacity 3.7.3 crash

TROUBLESHOOTING AUDACITY 3.7.3 CRASH
Audacity 3.7.3 Thinkpad x220 Digitalisation 48000 Hz stereo zu mono
The following setup is used for digitizing analog audio reels containing up to 3 hours and 20
minutes of audio recordings.
Workflow: Revox Studer B77 MK II (refurbished) via Motu M2 or Motu M4 to ThinkPad X220
Debian Trixie Audacity 3.7.3 Periodic but irregular crashes—i.e., the program freezes and
Ctrl+Alt+Del is also unresponsive. So power off and on and save the Audacity project.
What can I do to find the causes of these regular crashes so that a solution to this problem can
be found? Identical problem on two ThinkPad X220s same workflow as for a ThinkPad SL 510 (Debian Trixie Audacity 3.7.3) which performs the digitization without any crashes. Thank you for helping ! kapsar

Are you saying it freezes/crashes DURING recording? If so, try using Ocenaudio instead (just to capture and save) while you look for an answer. There is a Trixie version.
