[2.6.0 Alpha 2] Crashing Slicing at 90%

[psyvision]

Description of the bug

When slicing a fairly simple model PrusaSlicer is crashing at 90%. I have read some other reports here which suggest it is either supports or sequential printing causing the issue. This project has neither enabled.

Possibly same as #9470 - was OK when changing to T0

[lukasmatena]

This is indeed the same as #9470. One thing the two issues have in common is "TIMELAPSE_TAKE_FRAME" line in custom G-Code. This line is confusing the CoolingBuffer, which mistakes it for a toolchange and crashes after failing to read the new tool number. 2.5.0 did not crash, but the CoolingBuffer was probably fooled as well. I am unable to tell if it was observable or not and how.

The issue will be fixed in the next release, thanks for reporting this.

Thanks for the feedback @lukasmatena

I have the same issue when slicing with T1 or T2 or T3. The default print head T0 is ok.

Same issue here!

Please, wait until 2.6.0-alpha4 is released and retest after that. The original issue reported by @psyvision should be fixed there, if the rest of you indeed report the same problem (and not a different one that looks the same), it will be gone too.

@psyvision and others please can you retest the issue with the new alpha?
Thank you very much for your cooperation.
