Ah, it looks like the stack allocated for the app is used up completely:

rsp: 0x000000003C824000, SS: 0x0023,
CR2: 0x000000003C823FF8

Let me increase the stack size a bit for now...

[hikalium]

It should be fixed now after https://github.com/hikalium/wasabi/commit/1e71e0dc96213a6e3ea4ad67f67a75a8053d6329 . Please confirm and close if it is fixed!

[hikalium]

I believe this is fixed now. Mark as fixed.
