FCPX render error? Or update issue with big sur? Please help!

I am having an issue with fcpx. I had a whole project color corrected and ready for export. My computer updated to Big Sur 11.2.2 and now I get these random problems with clips turning a solid color. If I render the file the clips comes out this color or sometimes turns bright green. If I turn off the effects on the clip and then turn them back on, usually that will solve the problem - but as soon as I move on on the clip gets rendered again it can come back the same where I cannot render the project. And the error/glitch is random. Sometimes certain files will be like this. I will fix them. and then other files turn like this. I updated fcpx to 10.5.1

You can see the clip thumbnail knows what the clip looks like, but the viewer only sees Blue. And it will render blue.

I am using RED footage and the Red fcpx app which has also been updated. I am using the basic fcpx color correction tools and the fcpx custom LUT tool. The LUTS come from Triune digital. I checked with them and everything is good and up to date with the LUTS.

I deleted all my render files and rendered again - still have the problem. I ran the computer in safe mode to reset it, and still no fix. I deleted all unused files within fcpx.

If anybody has encountered anything like this please save me!
