Thanks for the report.
There doesn't appear to be any errors in the model and it sliced for me with my Ender 3 Pro active and the standard profile with normal supports and PLA.
You are still using the 5.7.0beta version. That is a test version before the release of 5.7.0 stable. The current Cura version is 5.7.2. Please update to a stable version be it 5.7.0, 5.7.1, or 5.7.2. Be aware that 5.7.2 has a bug that affects the startup. If you decide up upgrade to that one there is a post processor posted in the bug report (#19204 ) that will fix it.

From your log file is a generic error: "Backend exited abnormally with return code 3221225477!" The cura team should have your crash report.

I installed an Ender 5 S1 and your curaprofile and material and the slice finished but it took a while.
"Slicing took 1141.870280265808 seconds". It's nice that it goes to 12 decimal places. Rounding it off it comes out to 19 minutes to slice. (For comparison - the slice using my printer and normal supports took 4 minutes.)

This is in 5.7.2.

I had to rebuild the project from the files you supplied. If you would load the model into Cura and set up your slice, and then use the "File | Save Project" command and zip and post that 3mf file things would be much easier. It will contain the model, your printer, and all your settings.

Typically I would close this because it is for a '2 version out of data' beta, but I'll leave it open for the Cura team as the slicing time seemed really long for a model with only 140k surfaces.

With cura default settings it slices ok, but I have several custom settings that I need and with those I get these errors. I will get back with the 3mf file attached too.

Please find attached the 3mf file also.

I will try slicing with 5.7.2 and get back with details.

I'm not having any trouble with it.
My computer must have been having a bad day. The slice took about 4 minutes.
Just for reference, I print TPU on my bowden printer at 12mm/sec. 120mm/sec seems excessive for TPU, but you know your printer.

I confirm that with version 5.7.2 the slicing was successful and it took around 8 minutes to complete.

Hi GredValiant,
printing this TPU (from eSUN 95A transparent red) on the Ender 5 S1 at 120mm/sec prints very good (same quality as for 20 or 40 mm/sec). I did not try higher speeds as I red that TPU needs to be printed at lower speeds. I still need to fine tune the retraction and support settings (as I still have some fine strings when printing and the supports are harder to remove).
