Input LUT goes offline when re-opening project

The LUT I used is provided by built-in Lumetri preset called FullToSMPTE8, that can be found in Effects panel

Hi @Veniamin Kalman, thanks for reporting this issue and for providing the details. The prproj xml tag shared helps a great deal for narrowing down to the issue. If possible, do share the LUT file privately so that the fix can be verified sooner.

If it will help for developers (i hope so), there's two deferences in prproj xml files, one contains the problem described, the other does not.
1 - Project file with Error (LUT not found)

	<LUTAsset ObjectID="86" ClassID="d72d54f3-d40e-486d-8784-6fe0703dbb8c" Version="1">
		<Id>fc2569b9-c438-1de2-6a0c-5a1b2b5659df</Id>
		<Displayname>FullToSMPTE8</Displayname>
		<Filename>FullToSMPTE8.cube</Filename>
	</LUTAsset>

2. Working fine project file

	<LUTAsset ObjectID="86" ClassID="d72d54f3-d40e-486d-8784-6fe0703dbb8c" Version="1">
		<Id>a18cec07-3014-9476-076d-239fd00e0003</Id>
		<Displayname>FullToSMPTE8</Displayname>
		<Filename>FullToSMPTE8.cube</Filename>
	</LUTAsset>

  both tag containers are in <PremiereData> tag

Upd. the problem only appears if you exit the program immediately after saving the project.
If you first save the project, then do “File - close project”, and only then “Exit” - then the LUT is saved, the problem does not appear.
In general, the problem has not completely disappeared, Adobe should solve this problem in the next minor updates
