PrusaSlicer Error on attempted launch of application
HALP
PrusaSlicer worked just fine yesterday, but when I tried to launch the application today I get the following error dialogs. I deleted the App, reinstalled, and still get the same messages:
"Unhandled unknown exception; terminating the application"
"Internal Error: <unspecifie dfile> (14): '=' character not found in line"
I can't get past this. Any ideas? I'm totally stuck.

Anyone? I have uninstalled/reinstalled, and I keep getting the following error when I try to launch PrusaSlicer:
"Internal Error: <unspecified file> (14): '=' character not found in line"
Please don't tell me it's my OS or my hardware. My PC hasn't changed since last night, when it ran just fine.

Please try to delete the PrusaSlicer.ini file. For some reason, sometimes it gets corrupted. We were working hard to avoid that, but seems that the Windows API (application interface) for renaming files is not atomic, so if your computer or your slicer crashed when saving the PrusaSlicer.ini, it stored just half of it, maybe with some garbage at the end.

Have you determined a fix for the export config bundle crash? Will it be in the next release?

Yes, it will be fixed in 2.1.
There is an issue on https://github.com/prusa3d/PrusaSlicer/issues describing a workaround.

Bubnikv,
I see 2 workarounds proposed. I tried them both after reinstalling and deleting roaming config under my user. The one proposed by the guy in Germany was a failure. The other failed to export correctly after switching to SL1 as printer and even after switching back from SL1 as a printer to MK3S.
Are there better instructions to get this to succeed?

@bubnikv
Did we ever resolve this? im currently having the same issue. Can't even locate the PrusaSlicer.ini file

Have the same error - Can not locate the PrusaSlicer.ini on my whole C:
So .. meh - no printing 🙁

No real resolution in the latest download as of today. I still had to delete the file unfortunately. 🙁
RE: PrusaSlicer Error on attempted launch of application
Another one here. It was working flawlessly for the past 2 years. Suddenly today it doesn't work.

@david-5
Thank you so much! It worked.

The corruption of PrusaSlicer.ini on Windows happens very rarely, but it happens. It only happens on Windows and we were unable to reproduce it. For years, we are first creating the file as a temporary and first after it is saved and closed, we are renaming it to PrusaSlicer.ini. On all systems this operation is atomic, thus the file should never become corrupted. On Windows, this is seemingly not true, while this behavior is not documented. Why PrusaSlicer.ini gets corrupted we don't know. It may be, that you had a power outage. It may be, that PrusaSlicer was slicing at the same time and it crashed on the other thread. It may also be, that two instances of PrusaSlicer were modifying PrusaSlicer.ini at the same time however the operating system should not allow that due to file locking.
In the upcoming PrusaSlicer 2.3.2 we implemented a workaround - transactional saving. PrusaSlicer.ini is first saved to PrusaSlicer.ini.bak, then to PrusaSlicer.ini. PrusaSlicer.ini.bak is protected with a checksum. Thus if PrusaSlicer.ini gets corrupted, PrusaSlicer.ini.bak will be loaded instead. If our assumption is right, this will significantly lower the risk of the current PrusaSlicer.ini corruption issue.
