Hi! Thanks for reporting the issue, I've run into this occasionally while playtesting the currently available version on my laptop. While I couldn't reproduce it on my desktop PC, it seems to be related to the asset pre-loading process crashing. Usually, trying again to run the game would fix it (but sometimes it took another try).
In the new version that we're currently working on (which should have been labeled 0.3.0 in the devlog as I've just noticed, not 0.2.0 since that's the currently available version, oops) the issue doesn't seem to happen anymore, or at least much less frequently, after I made some changes to the pre-loading process.
