VP23 cannot use Flicker Control

I bought the standard upgrade to VP23 and installed it today. I opened a project that I had started in VP22. The project has 5 video tracks, 3 audio tracks and about 13 text / animated text tracks. I have applied flicker control to 3 of the video tracks. I can open the project in VP23, but once it reaches the point in the timeline where the Flicker Control is applied. The video freezes, but the audio plays. From that point the program is unresponsive. I figured I'd just finish the project up in VP22, but no can do. Since I saved the project in VP23, it will no longer open in VP22. I finished doing what I needed to do without running preview and completed the project. So I figured I see if I could render it. That wasn't possible either. The rendering starts and just locks up when it gets to the point where the Flicker Control is applied. It locks down tight. NOTHING can be done. No crash notification, it's just locked frozen. So I had to kill it in task manager, several times before it finally closed.

I tried several times to preview the video in 23, but it always does the same thing. The program locks up and I have to kill it. I reopened the project in 23 and went and removed all of the Flicker Control effects, and the project runs fine in preview mode and I am currently halfway through rendering and it's running smoothly.

Why can't I apply flicker control in VP23? I used it all the time in VP22. While it does cause the preview to lag and stutter, it's still useable. It also added a huge amount of time to rendering, but at least it worked and VP22 never froze up.

UPDATE: I spoke too soon! The rendering froze solid at 70%. After I killed VP23, I reopened the project and rendered it again. This time it froze at 63%. I knew I should have waited to install this until the initial bugs were worked out. Now I have to do the project over from scratch in VP22.

Though too late now, it has been recommended many times on the forum over the years to rename a project when moving the project onto a later Vegas Pro version so that the 'old' .veg project file can still be used in the older VP version if need be. And regular renaming of the project (e.g. name-v1, name-v2, name-v3) as the edit progresses is also a good idea just in case the latest .veg file corrupts for some reason - it's then just a matter of going back to the previous .veg file. Though some editing will need to be redone, at least the project doesn't have start all over. Keeping a copy of project .veg files elsewhere (e.g. the cloud such as OneDrive, an external HDD, memory card/stick) is also a good idea just in case of a C drive failure/problem on the computer - and I've had that happen.

In Vegas Pro 22, do you have Advanced Save activated under the Tools menu? If yes, you may still find a recent project save in the folder which has been chosen for advanced saving.

Otherwise, to get your current VP23 project back to VP22 without having to start the project again from scratch, there are 2 processes that may work:

1. Copy (Ctrl-A / Ctrl-C) the project's timeline in VP23 and paste (Ctrl-V) onto a fresh VP22 timeline. FX unique to VP23 won't paste and nor will project or track level FX, but common FX should paste; or

2. Using File/Export in VP23, export an EDL Text File and then use File/Import in VP22 to import the project into VP22. This method will only export/import the project's edited media timeline - but no FX at all.

@anthony-chiappette One thing to try on VP23 is to disable the hardware decoder to use: go to preferences, tab File/IO then set hardware decoder to use to "off".

See if that helps, please report back if it helps or not.
