I got this error when trying to change to the " APPLE PRORES 444 QX" format

I correct! The error of the unexpected closing when putting the "ScriptUI Panels" happened to me after the current beta! because I updated directly (the ScriptUI Panel remained configured, and I don't know if it happens in this case,) @JohnColombo17100380 

hello ! The error happens when I want to modify the format section (it defaulted to that after I got the error so I didn't go back and configure it) and I export without problems! , but if I enter the format section it happens again (I enter again out of curiosity) my GPU is a GTX 1660! Today a new update of the studio drivers was released, (this happened before I updated, so I have not tried anything with these drivers yet) on the other hand... I am using the latest version of the "Beta" I updated it today , and an error that happened to me was that when I opened the program and started configuring it (I placed a "ScriptUI Panels" and as soon as I put it in, it didn't give me any error message, it just closed! @JohnColombo17100380 

Hi @_Maik,

Thank you for reporting this issue in the Beta build.

Could you please provide the following information:

1. What specific version and build number of the Beta crashed for you? 
2. What are your system specs? This is very important since the error implicates your GPU.
3. Does this happen consistently when you select ProRes XQ?

Thanks again,
