Reset and Fresh Install both cause app to cease functioning

[AmaliaKalio]

After the 5.0.2.1 update pushed today, VRCFT was crashing as soon as it loaded parameters. I first attempted a reset from settings, which prevented it from launching. A full uninstall/reinstall gave the same results. Event viewer logs are below, with the referenced .wer attached.

Managed to track down an Event Viewer log from when it was crashing before I reset.

The program was able to recognize that an update to 5.0.2.2 was available, and launched the updater. After the update was complete, the error scenario in the first post seemed to persist.

[benaclejames]

Did you try a complete uninstall and reinstall of 5.0.2.2?

[AmaliaKalio]

Did you try a complete uninstall and reinstall of 5.0.2.2?

I did, yes. I attempted with both the .msix and .appinstaller files.

[AmaliaKalio]

This issue persists in 5.0.2.3.

[AmaliaKalio]

I was able to get v5.0.0.0 to run from a clean install. However, the same crash happened when I attempted to load the 'Module Registry'.

From there, I performed an in-place upgrade to 5.0.1.0. This came with the SRanipal module. It loaded fine and I was also able to access the 'Module Registry' tab.

Attempting an in-place upgrade from there to 5.0.2.3 presented the same immediate fault. Clean-installing back to 5.0.1.0 still works.

Rinse-and-repeat, going down one version at a time. 5.0.1.1 appears to be the latest stable version.

[benaclejames]

This issue persists in 5.0.2.3.

Could you provide a latest.log from this release please?

Have you tried wiping that whole VRCFaceTracking directory within appdata and then re-running?

That fixed it!

[benaclejames]

huh, don't suppose you have a copy of what was there so I can diagnose for the future?

[AmaliaKalio]

Wish I had backed it up. However. I tried a clean install of 5.0.2.1 and stepped through the reset buttons to try and replicate where I was at the start of this thread. The program would no longer launch, but the directory in %appdata% was also missing, strangely enough.

[tokragua]

I had the same problem and I also solved it only after deleting the %appdata%/VRCFaceTracking folder. @benaclejames If you want a zip file of the contents please let me know and I will send it to you via Discord.

Yes please! This would really help in figuring out why the crash was happening in the first place. I can be reached on discord with the username benaclejames

experiencing this now, No folder in %appdata% for VRCFaceTracking
Doing a full reinstall fixed it

[Codel1417]

It may be a permission issue as giving the Users group access to the appdata/VRCFaceTracking folder caused the log file to work
