Steps to reproduce:
1. Generate a The Void superflat
2. Run the following commands:
/fill -93 ~-1 -3 93 ~-1 3 soul_soil
/fill -3 ~-1 -93 3 ~-1 93 soul_soil
/fill -93 ~-1 -93 -4 ~-1 -4 crimson_nylium
/fill 93 ~-1 93 4 ~-1 4 crimson_nylium
/fill 93 ~-1 -93 4 ~-1 -4 warped_nylium
/fill -93 ~-1 93 -4 ~-1 4 warped_nylium
3. Spam bone meal all over the warped (green) nylium blocks. After a while, bonemeal stops working. This is because of extreme TPS lag caused by MC-175269.
4. Press and hold F3+C to trigger a debug crash.
❌ When the crash countdown reaches 1, the game stops responding. Closing the game at this point pulls up the "Game Crashed" in the launcher, but does not generate a crash report.
This behavior is inconsistent with debug crashes triggered during high TPS lag due to entities, e.g. a repeating-command-block villager fountain.

Confirmed for 20w13b.
You can update your own ticket, meaning you can add the affected versions yourself 😛

Confirmed. The server completely freezes, so does the TPS graph on the lower right. Can be reproduced easily with the provided reproduction steps.
Related to MC-175269.
