Titles not visible in preview window

Hi,

I have something really annoying that happens randomly and I have no idea how to fix it. When I add classic static titles to the timeline on any project, sometimes when I reopen the project the titles do no show at all in the preview window. I tried switching workspaces and resetting the workspace to saved settings. Also closing and reopening the project and deleting media cache. The only solution I found for now is restarting the PC completely. However that is really inconvenient because sometimes I have many other things running and it disrupts my workflow. As mentioned, it happens with any project at random.

I use latest version of premiere pro on a windows 10 PC, cuda enabled on an RTX 3090, threadripper pro 3955wx and 128GB ram.

Any ideas? thanks
