Minecraft Bedrock crashes after 5–6 minutes on PC in Realms, Survival, and Creative worlds

Minecraft Bedrock Edition on my PC consistently crashes after approximately 5–6 minutes of gameplay. This occurs whether I am playing on my husband’s Realm, a normal Survival world, or a completely flat Creative world. The game runs normally at first and then suddenly crashes without warning. Minecraft Bedrock is fully updated, my PC drivers are up to date, and the issue only happens on my PC. I am playing through Xbox Game Pass but am signed into my own Microsoft/Minecraft account. The problem occurs in Realms, Survival, and Creative worlds, so it does not appear to be related to a specific world. Resource packs and add-ons were previously enabled on the Realm, but they have since been removed and the crashes continue. The issue occasionally occurred before the most recent update, but it now happens consistently after about 5–6 minutes. The crash does not seem to be triggered by any specific in-game action and can happen regardless of what I am doing. Expected result: Minecraft should continue running normally without crashing. Actual result: Minecraft crashes after approximately 5–6 minutes of gameplay every time.
