Hi, I’ve been using/ learning TouchDesigner for about 2 months. Recently, after updating to TouchDesigner 2025, I started experiencing crashes/exits for the first time.
TouchDesigner repeatedly closes after around 60–130 seconds. It does not show a Windows crash dialog, and Windows Event Viewer does not show a normal Application Error / Windows Error Reporting crash for TouchDesigner.
TouchDesigner version:
2025.32820 / 0.99.2025.32820
Executable:
F:\Program Files\TouchDesigner\bin\TouchDesigner.exe
System:
Windows: Microsoft Windows 11 Pro, build 26200
CPU: AMD Ryzen 5 5600H with Radeon Graphics
RAM: 31.3 GB
GPUs:
- AMD Radeon™ Graphics, driver 31.0.12044.3, ~0.5 GB VRAM
- Radeon RX 5500M, driver 32.0.21043.19003, 4 GB VRAM
I reproduced it while opening:
- F:\TOUCHDESIGNER\Official course\TouchDesignerFundamentals100Examples\109\TDFundamentals-109-fields-in-POPs.tox
- F:\TOUCHDESIGNER\PRACTICES\experiment typography grid grow.toe
Both TouchDesigner processes were initially responsive, then all TD processes exited after around 2 minutes.
Things I already tried:
- Clean reinstall of TouchDesigner 2025.
- Fresh local profile/cache at %LOCALAPPDATA%\Derivative\TouchDesigner099.
- Windows Defender Controlled Folder Access originally blocked TouchDesigner, but I added TouchDesigner.exe and TouchPlayer.exe to allowed apps.
- After that, there were no new Defender CFA block events during the monitored run.
- All plugins were disabled/removed during the clean test.
- No Windows Application Error / Windows Error Reporting crash was logged.
- No normal crash dialog appeared.
I tried using WinDbg Preview, but I’m not experienced with it. WinDbg captured the process at termination. The stack looks like this:
ntdll!NtTerminateProcess+0x14
KERNEL32!ExitProcessImplementation+0xb
ucrtbase!common_exit+0xc7
libTD!TiXmlNode::FirstChild+0x439757

I’m not experienced with this, and I’ve been using Hermes agent to help file this report, if there is anything I got wrong, please let me know, thank you!
