Health plans: Are all Silver health plans gone? Is there a chance of anything changing if the shutdown ends?

Went to get new health coverage for next year and noticed that if the only filter enabled is “Metal level = silver” the health plan finder turns up zero results.

Then I saw this message

You or someone in your household are enrolled in a Silver health plan in 2025 that will not be available to you in 2026. A Gold plan with your same insurance company is available to you.

Your Gold plan may be more expensive than your current plan because the federal government failed to renew enhanced premium tax credits.

So, are that middle level of plan just gone? Is this a result of the shutdown? If they cut a deal tomorrow might anything change?
