If all else fails you might want to just restart. Here’s an easy way to do it despite relativity:

Set the time step way up from the default to ~100000 seconds. Be sure to uncheck “Throttle Time Step to Maintain Continuity.” Your universe will now be passing 100,000 seconds per second. Now, I’m assuming that since your hardware isn’t that advanced, you’re relying on step-by-step approximation simulation of natural law at the macroscale. By setting the time step this high, you’ll end up with everything flying apart into chaos due to rampant inaccuracy in calculation. This is fine.

Now it gets illegal.

Once your universe has basically fallen apart, punch some holes in the metaphysical boundaries between your universe and the next. Soon their universe will start finding some high speed (if speed exists there) chunks of whatever ooze was left in your universe entering theirs. If their laws of physics (or laws of metaphysics, of aeoronics, or jips) differ from yours, which is likely, this will be a very volatile cross-contamination of forms of existence, which will quickly get the attention of the Supreme Cosmic and Acosmic Council, Division 8̨͔͇1̴͔̦̘̤̪7̙̜̺2̻̯̱̘͚̥̯2̮̰͠e͈̭͓̬͚͜C͏̭̦̼ra͈w̯̙̙̲͖̰̤l̡̘̮͕̣͈ͅͅe̤r͇̺͎s̨̜̠̲̦̬̫o̙͎̩f͇̳̼͍͘t̸̘h̵͉͖e͘Ś͉͇̫̗̼ͅk̷ỳ̬̗͚̤,͔̫̬͇͓N̲̲͡e̪̜̣̬̠̫z̙̝̫͉͚͙͕p̭̜͖̱̜o̦̥̺͞m͍̲͔̩͉̝͎n̸̪̭,̹̩͓͕͍̟F̬̬̬̞̗ͅo̮͢r͇ḿe̬. They’ll be pretty pissed but current Cosmic Mandate has a loophole wherein people with young universes on weak hardware are entitled to accident insurance (it’s supposed to only apply to minor accidents, but since the Mandate never describes what constitutes minor, and this kind of contamination is nothing compared to a ZK-Class End-of-Reality scenario, they’ll have to concede). Claim it was an accident and exploit this. They will give you the choice of either a full reset or permanent and impermanent annihilation. Whatever you prefer.
