Warning: Unable to display symbolic object because 'symengine' was reset. Repeat commands to regenerate result.

Applying cramer's rule for a 2x2 matrix to solve for constants C_1 and C_2 but keeps returning "Unable to display symbolic object because 'symengine' was reset. Repeat commands to regenerate result". Hopefully not making an elementary error but recently updated to 2024a version and been having error message for other codes. I'm using syms, as I'm not provided with spring constant, n, or xi. Therefore I treat them as scalar variables. I appreciate any pointers/tips to resolve this problem. Thanks.

y = [(1-(k/2)), ((k*(1)^(n+2))/((n)*(n+1)*(n+2)))-((1^(n+1))/((n)*(n+1))); 1/6, -((1^(n+3))/((n)*(n+1)*(n+2)*(n+3)))];

Hi,
this seems to be due to a bug in R2024a which is fixed with the Update 1 release that is expected to become available to all users by end of next week (April 18).
The bug is specific to using Symbolic Math Toolbox together with clear all. I typically discourage using clear all as this clears more than necessary in most cases:
If you still experience issues without using clear all or after installing the update release, please contact Technical Support for further investigation.
Best wishes,
Harald
